A video review? Wow that's a first for me, thanks!
I know the game is much harder than I wanted it to be, I'll try to make it easier, or at least make more easy levels like for tutorials and stuff (better than the vague description and tutorial), probably the best idea. It's the sort of stuff it never crosses my mind when in a jam.
I really like the HUD and the checkpoints idea, I didn't think of that, I'll make sure to try them out. As for the acceleration problem, I'm using Unity's native gravity, just changed the direction, so I don't know what to do about that, I could make it so it doesn't have gravity and I put in a constant velocity, but then you couldn't do those bounces you need in order to get out of those "bowls" in the levels and I don't know if it'd fell natural, but it may be better anyway and I'll try it out.
It's really nice to be able to see someone actually play it, so again, thanks for the video review!
