Nice game! I love the idea of needing to complete the levels in the least amount of shots and mirrors to get a higher score. I feel like the levels could be cut down a bit, a lot of them use the same mechanics and concepts as previous ones with not a whole lot of "new". For example, maybe instead there could be just a few levels that show of the basics, then move onto using the prisms. Also not sure if this was intentional, but you can shoot the light and then switch to build mode and move around the mirrrors while the light is still moving. However, that could be an interesting idea to explore, but yeah just wanted to point that out. Otherwise, fantastic submission!
