That was fun, the music was great and suited the game well despite being AI generated. I experienced the known issues you mention about mouse difficulties in the menu, but was able to work around it.
Look like you had a lot of fun with trying out different perspectives and camera angles, which was generally pretty cool but...In the later few levels it became difficult land certain jumps, partially because the camera was in a sudo-isometric angle where movement was now all done diagonally is not something i find especially easy with a keyboard, but certainly less of an issue with a controller), and partially because the camera often changed mid jump meaning you had to alter your orientation, and how you were controlling your movement in the air, because the context had changed from when you started the jump.
Beyond that I felt a little inconsistent, that in some levels you bounce on top of dumpsters, other levels its the cars, the height of the bouncy changed based on whatever was needed for the particular jump to reach some candy etc, and then some buildings you can stand on top of, and others you cant.
This all made it a bit harder to really fall in love with, but overall a decent game, with some interesting ideas for sure. Good stuff!
