Cute wordplay!
I liked the premise of the game and thought it was pretty fun to play. I did find the controls pretty frustrating, but I stuck around because I wanted to see how big I could grow my planet!
The bugs were super annoying to shoo away, but in retrospect, this was actually a pretty good simulation of certain bugs... there are definitely some types that seem to stick around too long when you try to shoo them away. :-)
I really liked the visual of the growing planet size at the end of the game to show the level you achieved... I think it would be cool to show each size name along with the animation.
Good job!
