Cool game. I liked the gfx and the levels much. Good mixture of enemies as well. Well done. Played for almost 2 hours and unlocked almost everything, but I never found a button. the 2 things I missed the most are: a map, and checkpoints. it would be cool to teleport at a checkpoint somewhere far, maybe with a percentage of your power removed. also, you “shift” key mechanics was sometimes too much for my brain :-)
But overall, very good game.
