40 minutes but finished! Very challenging and hard, cool idea. I thought spider&vent level was hard, but gears level later was crazy :D
I feel like space might not trigger jump correctly when you are on downward tilted platform (left side up). I think game detect you are in air and won't let you jump if you move right first?
In ascend level using multiple pistons - you can actually "catch" wall (just above piston) to not fall to the very bottom.
Music was very nice and fit well.
