The first things I noticed were the performance issues - probably mostly a issue with the WebGL build. Standalone would be nice, although it only lagged when looking at certain things (like the large fire at the start), so it wasn't a huge issue.
The art is beautiful! It looked very nice and was impressive for a game made in 48 hours. the music especially created a very unsettling atmosphere. Very nice presentation.
It was a bit difficult to figure out what to do at first (as the light beam can connect to anything, including props and level geometry), but pretty fun once I got the hang of it! Good job :)
