Giving this a 5 for the music alone! Especially in the bounce level. Some really interesting puzzle platformer levels there, and I loved the "diode" reference. :D
The game is entertaining and well-made, bar one thing. The movement is WAY too finicky. Momentum carries you too far, too fast. When you BARELY tap the direction key in mid-air, but land running and enter lava, that's no good. When you end in lava on the OTHER side of the target platform when trying to compensate for this effect, it's bollocks. In the end you're limited much more by the eccentricity of the movement, than your skill as a player. This does not a good game make.
3/5
Only levels 16 and 21 stumped me so bad I had to depend on a walkthrough. Those were devilishly hard. Many later levels though, like 24, 25, 26, 29, and 30, were incredibly easy.
04:26:77.5 with 7 deaths. Don't think I can be arsed to do any better.
I always die at least once on the ones that require you to refresh/go to credits, the ones that use the mouse, and the headwind one.
