Seems i missed half the features on my first play through, did not notice the double jump, the abilities, or the themes. Played again did it a bit better but still no where near the top. Would adding a full screen option or larger play screen, because its pretty tiny and difficult to see whats going on sometimes, also sometimes i found it difficult to see what the non-active block colours were (maybe just my slightly colour blind eyes) , so found myself dying a lot. Also sometimes the level layouts end up with walls of the same colour that are difficult/impossible to get through which is annoying, maybe after random generation break up any long chains of the same colour). I still thought the underlying mechanic was a cool idea and pretty fun just currently a bit frustrating.
Thats something I ran into too. Currently redesigning the tiles so that each color is clearly represented even when inactive. Also, playing with the idea of levels with different heights to reach for completion - so players don't feel defeated by failing one screen over and over. Thanks for the feedback.
