This game is a lot of fun! I spent about two hours trying to optimize my laser. This game has great visuals and awesome music, and a functional tutorial for a jam is impressive!
The biggest piece of feedback I have is the player needs to be placing the lenses more often, and I think destroying a placed lenses should refund at least part of its cost. I placed down a lot of mirrors only to find out they weren't quite right, but destroying them would be a waste. I only destroyed ones that were actively harming my setup. I played the game for so long because I was enjoying myself, but if you juice and polish it just a bit more you have an absolutely banger game.
Full marks from me, great job!
