Yay, another one. Some thoughts:
* Full-screen is easer for me to play than windowed, so yay for that.
* The dying animation and sound effect make dying more fun, which is good for making you want to try again.
* The music and background effects combine to give it something of a mesmerising quality.
* As someone with limited time (and patience), I appreciate the checkpoints and saving.
* It doesn't explain that arrows move and alt+F4 quits, but that was pretty easy to figure out for myself.
