I liked your entry. It reminded me a lot of SpaceWar which I was really fond of back in the day. It doesn't really hit on the Tiny World theme though because the planet is normal sized as seen by it's relative size to your ship. You are just looking at it zoomed out.
I really liked this entry, it was fun. I didn't like dying too quickly, and it was annoying to tell the difference between the bullets and ships, but it's a really solid concept. Good job!
Still, a fun game!
