I liked the level design and the clarity of the art. Really liked how you implemented the switch between the 2 worlds. I had the same idea for my game, but I put a bit more focus on the switching between worlds part. The only criticism I have is that I feel like the controls are a bit too sensitive, which make some of the more precise jumps in the levels a bit frustrating, but overall I liked this game.
Thanks! About the sensitive controls, I’ve had a few playtesters who reported that the game feels a little too fast (and thus, sensitive controls). However, adjusting the game speed isn’t an easy fix, since I’ve locked the whole physics system to the framerate, so I would have to rewrite it basically from scratch.
I’m going to rewrite it anyway because the code quality is absolutely terrible, but I won’t be able to tell when I’ll do it (school starts very soon).
Good luck with your rewrite, if you ever get around to doing it. I would recommend to play around with linear interpolation for player movement, if you haven't done that already. From my experience, interpelation helps a lot with making the players movement feel a lot less sensitive. Anyway, great job on the game.
