Just finished it. Rabbit is free and became my friend. I managed to cheese the game a little bit. I landed on spikes, reduced my velocity and pressed R. My velocity didn't return to normal and I was moving slower and dragged the box slower. Maybe it's not velocity, maybe it's time that didn't return to normal.
1. Overall the character feels too floaty, like in the water. In Unity, if I want to use RB for a good jump, I mess with linear drag. I create a drag change within n(0.15) seconds from start drag 10 to end drag 1 through curve. And I set gravity and impulse high. It makes a very cartoonish snappy jump. But for platformers they generally make custom physics.
2. It's hard to control the crate, it doesn't stop when I don't move my mouse, maybe there should be an invisible zone on the mouse position where the crate doesn't continue getting force so it can stop better.
3. I like the idea. Maybe I would love it more if I get different mechanics with my telekinesis ability instead of draging the crate over and over again over very long levels. Felt like a chore.
4. I would work with text a bit differently, didn't like that it just stays in space and doesn't disappear, floods the picture overall. I like crate reactions though.
5. Physics is hard, I make a game with physics at the moment and there are a lot of workarounds that I have to use so it doesn't break the game.
