Thank you, I had a lot of fun making these illustrations (I wish I could have done even more). For now it's just a concept, but if I found a developer interested in the project we could talk about making it real!
I am a (fairly) competent developer. If you were interested in building it in GB Studio so that it actually ran on Game Boy hardware, I'd potentially be down to chat! Though that'd come with a fair deal of limitations feature wise, since ya know... old ass hardware.
