Been a while since I played the game (2 months) and I nearly forgot to write a little feedback, really happy I remembered to do that because I really really like this one.
The concept is insanely versatile for unique puzzle levels that all follow a certain rule but can still be insanely surprising.
It's hard to have a simple ruleset that a player can understand but which also allows for tons of surprises while not breaking any rules (I've been kind of obsessed with stuff like that recently because I started watching some Mario Maker Troll levels which are absolutely insane in that (atleast for people that know the language of those levels))
The physics felt a bit awkwardly floaty at times but it really fits the feel of an oldschool newgrounds type of game. And a faster jump might also mess with the playhead shenanigans because adjusting those does need a lot of thinking which you sometimes gotta do mid-jump.
