Wow what fantastic design! That you go from one end to the other and only the end changes is really great!
I do think that the death zones might have been made a little more forgiving but maybe I'm just bad... I did sadly have a crash at the tail end of the 5? level and had some gnarly lag spikes each time I shot of from a ball for the first time each level.
The charcoal was a nice idea but I did not quite get why it had to have a button to apply it?
The sound design is fantastic, the pling when you hit a wall is perfect! The minimal art-style lends itself great to this game and is executed beautifully!
