As others have said, very cool light mechanics. Was glad to see the way the lanterns worked with the mechanics, as well as providing helpful checkpoints. I'm not a very good platformer so I did find the later levels very hard. One suggestion I have is maybe allowing the Up arrow or W to use as a jump button as well. The most inconvenient thing I found was trying to quickly use the mouse in between jumps, until I started using a/d + space with my thumb, which I still found a little cumbersome. Some of the enemy triggers felt a little wider than their sprites which also led to some frustration. Despite my complaints, this is a very cool entry and a great usage of the mechanics. Nice work!
