Very cool and well-put together game! Presentation is solid and I'm making my way through, bit-by-bit. I like the secrets that are hidden around levels, gives it a real sense of exploration (though I thought the "Hey You!" was just part of the music track at first, haha). Really enjoyable, though I do think there is a lot of confusion. For one example: I dunno why there needs to be two types of spikes: the block spikes, and the rotate-y spike balls. You'd think it's because the rotate-y spike balls are affected by gravity, and the block spikes aren't, but some spike balls aren't affected? Very inconsistent and frustrating to keep track of. Feels like the game also goes too fast into precision-platforming-based levels instead of puzzle-based levels, and those types of levels are a bit too frustrating to navigate with these controls. Still, the general feel of the game is very positive for me!
Also, there's a little bug for me where the music doesn't start after selecting a level until you die once in the level.
