This was an excellent and brief platformer experience with a great use of the theme. I love my AI's sunglasses. The art on the page banner and in the intro and outro of the game are wonderfully done! Really nice looking stuff there.
HTML wouldn't run and I did have this issue on Mac:
I thought maybe you were using GMS2, but you used Unity. The last jam I participated in I noticed not a single Mac build would run. They all had similar errors. Even my own submission, I could install it and play it on my own machine, but not on any other Mac, including my own laptop, so ... who knows what's going on with Mac builds.
Luckily I keep a PC laptop for jams and had a blast with your game. The control options felt a little odd, so it made for tougher platforming than it needed to be, but I appreciate the generous jump height and nice control with floaty gravity.
I don't think there's any reason to make the player select the next level, you can just begin the transition as soon as we reach the goal. If there was a reason to replay a level, say there were hidden items on each stage or extra challenges/pickups along the way, maybe I'd want to try again, but if I want to exit I'll just close the program. When I'm in the zone I just want to jump right into the next level, not have to go back to my mouse each time.
Overall, great work and your team should be proud.
