Really good game and a unique take on platforming. I really liked the first few levels as you were teaching the concepts.
I had two issues with the game, though. The first was that it would have been nice to have a timer counting down the weapon change or maybe even something like tetris where you know the next weapon, but that's it (I am on widescreen, so if a timer or something was cut out of the frame, ignore this). Secondly, for a platform with not a lot of control, the hitboxes on the spikes felt really unforgiving. I landed once probably 85% on the ground and 15% on the spikes and died from it, and that didn't feel quite right.
Really good game, though. With the theme being out of control, it was nice to play a game that felt out of control, but not just needlessly difficult/annoying.
