Thanks for playing the game! We did take the approach of teaching the mechanic slowly and then showing some more interesting things we can do with them. Yeah, when levels have too many lasers, the GPU burns ;(. Given more time we probably would have tweaked the level design on it more. I actually did a pass over the level to make it a bit harder cause we got the feedback it was too easy from a few friends. But yeah, it is essentially just a matter of discovering the right route through the lasers.
Anyway, thanks for playing it and glad you enjoyed it! Will try your game as well when I get some time :)
