Really cool game - I always got glitched either into the floor or into a corner right before the boss.
I got really good at getting there in under 2 minutes 30 seconds tho, hehe.
Just a single checkpoint somewhere would've made it so much more enjoyable.
Some sounds would've been nice as well, but honestly I enjoy silence more than obnoxious sound-effects.
Well done - was actually really fun to play (and try to speedrun) except the glitching into walls and dying to the boss through the ceiling part. Other that that I enjoyed it a lot.
