It took me a while to update to PICO-8 0.2.1b, so when I upgraded, I took the opportunity to play around with the pattern feature implemented a while ago. I also wanted to try out the new oval tools. The result is this little guy. I wanted to draw with only shape drawing tools, and used a simple table with some runtime values. It could probably be cleaned up, but I think it's a cute enough demo to learn a few new features. I enjoyed figuring out how to draw a bubble without using the pixel editor.
If there are any style or logic improvement suggestions, please share them! The screen edge collision logic isn't terribly good, so I know that needs work.
