I found the kitty! It would have been nice that once I did, maybe it followed you out or something.
I like the feel and look of the game. The hidden spikes were a little mean, but handy to get back to the starting room.
The blood effect on the screen was cool, but by the end it felt like an unnecessary hindrance to my vision as I went along. Maybe if you reach that point the player should have to start over?
Overall nice job though!
