This is fanart of my favorite obscure Flash game protoganist. He's got no name, as far as I'm aware, but 4399 descriptions imply it's "Cantaloupe" when translated (poorly).
As I'm nice, here's all of the Flash games: https://archive.org/details/honeydewmelons
There is one game (all in Chinese, but basically just "Honeydew Melons Adventure 4") made in Unity that's not in here, you can easily find it on FlashPoint https://flashpointproject.github.io.....f-e1d360a8013b
