Ah, a fellow pufferfish-game-maker :D. Really like this, such a simple mechanic with lots of depth to it.
I can't decide whether I find this game really enjoyable or incredibly frustrating (it's the former). The random nature of the level generation did seem to have a big imapct on the length of my runs and I found a couple obstacles constanstly causing my demise, but with practice I imagine that would be less of an issue.
