The opening animation was amazing, I love it so much.
But also in general the game was nice and challenging, good level design. Took me 14 minutes lol, but that's probability because on the final level I decided to learn pixel perfect dodge and constantly died for at least 5 minutes. Plus for the options menu too, I had a problem where the sound had lot of high pitch "glitches" randomly, so the options were really useful, though sad since the sfx overall were nice.
(Also lol, love to see others also going for the "Superhot" mechanics :D )
