That was fun! Wish there was more! A couple of notes ( outside of some obvious issues ):
- I think slowing some of the friction down would be more optimal. The player just seems to slide to much. If you expanded this with more difficult levels it could become and issue with sliding off platforms to your death
- There are glitches I am sure you are aware of, but just in case: Jumping below or into the frog from the side will make the player stop mid-air. Audio continues to play.
- I figured out that to complete the puzzle with the mouse and the lever and the frog and the lever, all you have to do is simple grab the mouse/frog, hover them over the lever and put them back where they were. Idk if this was intentional but might make for better puzzles if you make it so that you have to choreograph the timing/movement of the mouse/frog.
- Could have used some quirky music in the background. :)
Overall great work! Was pretty fun! wish there was more!
