This looks like your first game submitted to a game jam? Congrats!
Here are my notes, I hope you take it as constructive feedback:
- I did not understand the light system initially at all. I thought the browser version of the game was broken and the platforms were invisible. It wasn't until I read @AsePlayer's comment about the lighting effects that I went back and realized that somehow I could switch lights and they'd show the platforms.
- I was able to skip a lot of the platforms (I only needed blue & red) to beat the whole game
- I did not find the controls intuitive. I dropped the more than half a dozen time by mistake and each time I was scared I'd move and lose it forever stuck somewhere in the darkness lol
- Probably adding a light respawn is a good idea because of the above
- More expansive level or other levels would expand the rewardingness of the game
Best of luck, hope to see more games.
