When I first opened the game, I was like 'What is this?' haha. But then I opened the menu, the sounds kicked in, and I totally got into the vibe. I'm having a surprisingly good time right now! To be honest, I don't see much connection to the 'Wave' theme, but you managed to make something really enjoyable regardless.
Also, I laughed so hard at the GitHub link ('http://I don't have one')! 😂 Best repo ever. Congrats!
