Thanks for checking it out!
There isn't much animation to it yet, just the fly enemies (and one other enemy type). I actually only got around to throwing in those animations right before submitting, so I plan to expand on it (and enemy variety in general) in the future. If I can figure out how to animate the background tiles, I'd like to do that with the waterfalls and such as well.
The glitched screen is likely the result of a bug dealing with room positioning when trying to respawn at a checkpoint (I haven't had much time to bug test outside of a quick run through to the end screen). Do you by chance know which statue you had last visited when you died?
