Wow! This was a really fun game. My thoughts:
- Really fitting music.
- I wish there was more of a theme to the game. Like maybe the levels could look more like hotel lobbies or something.
- Nice enemy variety. I thought the game was gonna go on forever with no changes at first, so the cacti and especially the boss fight was a great surprise.
- The movement of the character is a bit choppy. Perhaps you could have the character accelerate for a short while before getting to full speed, (like Mark talked about in Platformers Toolkit).
But yeah, this is great for a 48 our project.
