A nice, simple, arcade romp.
The player character and enemies are cute! The movement felt nice and fluid enough. Music was relaxing, I like the xylophone. I kind of wished there was a background, but oh well. 3 hours isn't really the most amount of time in the world.
Speaking of, nice job getting it within the time limit!
Your project reminded me of when I started out using GameMaker. Solid effort all around!
