You can Double JUMP – Map Screen update

MapScreenHello everyone, I’m still alive! Also I have become a father to the most lovely black hole of time imaginable. You can Double JUMP has also had a child if you can count a child as being a map screen that is. The shot above shows the map of the first world named Grassy Hills, it’s currently a little bare on the details (trees, rocks etc) but the keenest among you will notice exactly what is in store for you for You can Double JUMP’s features (for you).

Heterodoxxed – v0.9.5 released!

Aside from the embarrassing performence that comes from not being very good at my own game (see video above), Heterodoxxed has some new touches and fixes, listed below. The most notable changes are improved thumbstick control (no more twitchy movement) and an improved/final look for the Truth Bar and Truth Bombs which now use a cool colour mask shader.


– Improved Truth Bar look.
– Improved Truth Bomb look.
– Incresed Truth Bomb power.
– Wall Type Projectiles are now removed by Bombs.
– Fixed twitchy thumbstick controls.
– Fixed Current Music window not shrinking correctly.
– Fixed music playing for split second when muted.
– Menu music now loops correctly.

I hope you enjoy the new changes and if you can beat round 6 on Hard, then I applaud you because I can’t even get close.

The unorthodox shmup, Heterodoxxed is OUT NOW!


Heterodoxxed is a simple shoot-em-up where half-truths, slander and bad words must be destroyed before you’re crushed by the outlandish lies.  There are only three rules to follow in Heterodoxxed.  Shoot, dodge and collect.

The last rule refers to every letter you destroy leaving behind Truth bits.  Once you have collected enough bits, you are granted with a bomb, increased weapon power and more space to again, shoot, dodge and collect.

I hope you all have fun with this simple but satisfying shooter and don’t forget to let us know what you think!

Heterodoxxed alpha out soon!


First let me say that I hope you all had a lovely Christmas and a great new year. Here’s looking forward to 2015, which I hope turns out to be a better year for gaming. We didn’t get as many great games out last year but with You can Double JUMP coming out this year, it’s already looking promising 😛

On point now however, I will be releasing an alpha version of Heterodoxxed (the GamerGate themed side project I’ve been working on) at some point over this weekend so you all can play it. It took a little longer than expected to create but the simple shumup gameplay coupled with a “collect Truth Bits to level up” system, is a lot of fun and with the awesome techy beats of Tim N’s ( driving it all along you’ll be dodging and collecting with style.


I very much look forward to creating the page over the next few days and releasing the latest build of the game.

Until then, take care.


GamerGate Game – Update #2

ggg2After a lot of writing, thinking then surprisingly only a little coding, I finally have a somewhat ok word spawning system. It’s far from perfect and still needs an algorithm to spawn shooty things on the words. On the whole, the game is finally playable in a basic way.

I’ve changed a few things from my original design and simplified a couple of areas. Before, the truth bits you collect counts as a currency but also as a shield, so when you get hit you lose your saved up truth bits. This was extremely frustrating, so now you have no shield and when you get hit by an enemy bullet the lower portion of the level (or sea of ignorance as it might be called) will rise up creating less space to move down from the falling words. Gameover happens when you’re crushed by a word against the sea or the sea crushes you against the very top.

The truth bits collected for destroyed letters can no longer be lost and instead of spending these bits, you spend single tokens (dumb name I know). You get a token each time you fill the bar on the left with truth bits and you can then decide, on the fly, whether to upgrade your main weapon or lower the sea a bit or explode a truth bomb (massive damage and removes any enemy bullets caught in the range). They all cost 1 truth token.

After I have finished all the features for the word spawning system and added some kind of options selection, I will upload the game to and look for someone in the #GamerGate community who will create the art so that it looks swish 😛

With any luck, my next post will have a link to download the game and I would love to hear what you guys thought.

GamerGate Game – Update #1


As I mentioned in my previous post (sorry for the delay by the way), I’m having a short break from developing You can Double JUMP so I can work on something completely different which is related to the consumer revolt GamerGate. My idea for the game as you can see above is a “shumup” where you have to shoot negative words and collect truth bits to not only charge your shield but to gain enough truth to upgrade your weapons. The speed and sizes of the words increase as time goes on and I plan to have three modes:- Normal, Hard and Endless.

The design is pretty much all thought out and I have to complete the word spawning algorithm, add blocks that fire at you and a few power ups.

Sorry for the hasty post and I hope to have more for you next week 🙂

Dev Log #4 – Time for some honesty

Over the last few months, there’s been quite the stir in one part of gaming and it’s mostly focused around the hashtag #GamerGate on Twitter. You may have heard of it as people who want journalistic ethics in games media or as people who want woman out of gaming. Whatever you may think of the hashtag and the people who use it, I want to make this post because I feel some honesty about where I stand on the #GamerGate issue should be made in a somewhat official capacity.

Where I stand
Now hear me out. I wholly support the notion that games journalism should be more transparent by disclosing relationships and to not collude with each other. When I saw the 10+ articles all talking about the same thing, I firmly believed it was an attack on the identity “gamer” and it seems to be a backlash to claims to conflicts of interest against certain individuals. Also, I shouldn’t have to make this clear but I will anyway. I condemn all acts of abuse, harassment, doxxing and threats of any kind. I feel that the strong focus on these types of threats not only make other potential attackers more tempted but also it ruins any possible discussion and distracts completely from the very likely claims of corruption and collusion and in the case of the articles, well it’s pretty blatant collusion.

Double Jump development
So now that I lost some of you let me discuss You can Double JUMP a bit. Development on DJ has been slow this year and I have to be honest that after nearly 2 years in development I’m tired and need a proper break from DJ, at least for now. The laser focus I had in the first year has wavered a bit and I’m struggling to think of new and original level mechanics that feel great to play.

New game
The reason I mentioned #GamerGate and DJ in the same post is because I’m going to use my time away from DJ to design a small game based on my experience of #GamerGate. I’ll be revealing the game in more detail tomorrow. Some say it’s suicidal for a gamedev to support this idea but I’m not making games to make millions. I just want enough to keep making games and to put food in my family’s tummies.

Thank you for reading my ramblings and tweet me @MariosKalogerou if you want to discuss anything about #GamerGate with me. We could discuss it here but a public forum is more ideal for that kind of discourse.

You can Double JUMP (v0.3.6) – Gameplay teaser trailer

So, roughly 6 months after I first proposed making one of these, I finally produced a new gameplay video!  I kept it short and sweet so it’s a bit more action packed and I should point out that nothing shown in the video is in it’s final state.  Actually, two of the levels shown are so bombastically hard that they may not even make it into the final game. See if you can guess which two.

The background music was created by Tim N ( and is used within the game as the overworld track for world 2.  I hope you enjoy the gameplay teaser trailer and I would love to hear what you think!
