The controls are really unintuitive, but in a weird way that just made it way better once I got the hang of it and the way gravity lowers and the game gets easier as you ascend is also quite nice. I don't wanna brag but I got a score of 626. Though I will say that it's somewhat disappointing that nothing happens once you reach zero gravity, would've been cute to have a little ending there.
(here's my proof btw. Also something might be wrong with the way the objects spawn as at one point the basically start spawning behind you, unless that was intentional ¯\_(ツ)_/¯ )
