Entertaining, as kids' games go
Pretty well put together game here. I've thought about making a game in that drawn-on-paper kinda style, and it was pulled off well in this case. The jump didn't work in this build, though perhaps your game is in admin-approval limbo at the moment. Either way, I don't think a jump was necessary. Not being able to jump provided the only serious challenge of the game. Using clever navigation of the springs and ladders to evade the AI was decently entertaining. That said,the AI was largely perfect for its purposes, but there were a couple of places where it would get stuck in a two-block area housing one of the tokens, so you really had no choice but to get hurt. Course this is rare, so you'd probably never die from it, but still a slight bother. Two more bits of constructive crit and then I'll shu'up. The bomb aspect was really underused. I actually forgot it existed for a span of about 15 levels until it was necessary again in level 22. Also, the level repetition was kinda weak. The game was plenty long with the number of unique levels it had, so the repetition seemed pretty unnecessary. Could have just added those levels as a 'mode B' or something.
Anyhow, all of those are just suggestions on how this could be better. It's already a great little game and I stuck through it happily till the levels began to repeat.
