Not my thing, but for a first game, it's pretty alright.

On a note though, two things. I personally think you gain weight way too fast, and I'm not just saying that as a person who doesn't really like weight gain. It makes the game quite a bit more difficult than I think it should be.

Also I know you're really proud of those game over screens, but they last way too long. How long they take specifically isn't the problem though. The problem is that they're unskippable. While people may admire them the first few times, putting forced waiting between failing and getting another try is frustrating.

Other than that, I think it's cool that you made a gameboy game~
