That was pretty nuts.
The fast pace and music really kept you hooked.
I cheated a little, by clipping through walls. Not sure by how much though. Certainly only later into the game, I only used it to double back on bad paths I had taken... and maybe I abused knockback to get a couple of places I shouldn't have been able to. Who's to say?
And I think I managed to beat the game without getting the third power-up. Not sure if it wasn't included, wasn't necessary, or my aforementioned cheating contributed.
I'll post ay gameplay recording when I upload it.
