Amazing, gameboy vibes. Loved it. Needs more! I couldn't beat goosebert :( the big balls are difficult to dodge once you run out of mirror power especially at the end when there are lasers happening at the same time. Probably by design, I'd say it's probably pretty well balanced. Would be more fun with a 2nd player but the pace was slow enough so I could play both at the same time pretty much.
Congrats on your submission and keep building :)
