I really like the music and how it syncs with the lasers but I think it's a little bit too hard especially when the rat shows up.
Also, as Charlie said, the game bugs and you can continue playing with a negative score, not sure when it's caused
thanks for playing its nice to see other play one of my game, about the bug I have no idea, it didn't happen in testing so I'm not sure (my theory is that is a bug when transferring from scratch to html as I didn't playtest after converting)
