Overall you did great, it was mostly bug-free and had an actual ending. That's tough to do on such a time crunch, respect++
Couple things I especially liked:
- Had a clear ending and progression of difficulty
- Including a 'how to play' in the main menu is always nice
- The audio didn't blow my ears out and force me to lower my system volume
Here's my thoughts on how it could be improved:
- The light visual is cool, but kinda hard to notice. I'd recommend setting the global light lower so it's more obvious; it'd also be great if you had the light shine on the background. Obviously that wouldn't work with your chosen background, but having the game be set underground, or having some rocks jutting up just behind the player for the light to shine on, would make the effect much more noticeable.
- The level design is a bit odd, the first level felt like it was the hardest, then the rest of the levels felt reasonable. Also the branching paths felt a bit useless, I can't look ahead to plan my path, and both paths always have a carrot, so I always just defaulted to dropping down.
- There was a level with some shallow water that didn't kill me. I felt that was odd since you established that water kills bunnies. I assume that's a bug though.
- The jump is a bit awkward, always being a full strength jump made the platforming kind of rough. Honestly that's a bit nit-picky, I know it's unrealistic to learn how make a good feeling controller during a game jam. Still it's a problem because the jumping is the core of the game.
Sorry for the essay, your game is a cross of things I love to yap about. I hope you keep making games and enjoying jams!
