Happy it please you! Actually the code and the sprites are not the hardest aspect i met when i developed the game, it's the levels design who is the most challenging.
Yeah, the default keys are not the most intuitive i will change that for the next demo.
There will be an abilities select screen, so for now, (except if you developed it), you can't really know what abilities does. i'm a bit sad you don't enjoyed the slow time ability through :-/
Sooner, but we can barely call it a demo :'D
Ps: I plan to create a easy lvl editor screen when i reach suffisent behavior and enemies but shh, it's a secret.
