I'll probably be redoing all of the levels in the next day or so to use different tilesets and a different hero.

I really like the zombie graphic. Here are a few suggestions:

1. Increase gravity. It feels a little floaty.

2. Maybe entering a door the down arrow key. You could later use enter, space or whatever else for another action or opening a menu.

3. Do not require pressing spacebar to go to the next scene. You could have the black screen set on a timer instead. Maybe 2 or 3 seconds to show the next room and then automatically go there.

Thanks for the suggestions. This is my first platformer and I've found that the physics are really tough to get right. :) I haven't tried it yet but I'd like to get this playable on a mobile device. The controls (jump, left, right, open doors, use items, etc.) are going to be really tough without a keyboard.
