Neat game! I found it a bit frustrating being a speed run kind of game.
I like the concept even if it can be a bit frustrating and cheap feeling at times. The levels were all pretty clever, with a lot of traps I hadn't expected the first time but then had a "well duh" moment about it once they trapped me.
I got 109 deaths and 6:03 as my time. So I'm certainly not the best. But I did manage to finish still and had a good time figuring out some of the trickier screens intended path!
I did find one exploit, restarting the game with R doesn't reset your double jump state, so on the first frame of a restart you can cheese some of the platforming. If intentional, there is probably a speed run that is amazing using this trick, though it would cost a life to respawn, so it doesn't help for the perfect run.
