This was a fun and cute little Tower Defense game! A genre I'm not really fond of, but that I could definitely enjoy in this game, which is a really good sign! The audio is just delightful, both the music and the sound effects are super gameboy-ish, and although the graphics fall a bit behind in that sense, they still resemble those of a GB game! The gameplay is simple and easy to understand, although there is a lot of information to be learned at once, right at the beginning, which confused me a bit!
All in all, a fun experience, great job! :)
