That's the high score I got after half an hour. I'm not that good at these games. This was certainly well made. (Do the animations use Spriter by any chance?) There's a buggy room with a switch. Sometimes you'll get stuck on the door. Otherwise everything seems to be working well. There seems to be a large difficulty spike from the room with lots of fire (which is very sensitive) onwards, which I think is the room after the aforementioned one with the switch.
Great presentation and very challenging gameplay. Probably sets out what you intended to do though for those who love this type of game.
