Ehh
No offense but I think it's not very good. I have a few reasons (more like suggestions)
1. Use the mouse as the ball instead of the arrow keys.
2. items came a little to often.
3. Make the death kinda like the mine, it takes chunks of it away at a time.
These are some suggestions I think are pretty cool if you could put them in if you made another game. But other than that, great ;)
