My game is a completely hand-drawn platform game that takes place entirely on a piece of paper. This isn't a sketch, this is my live game:

It's almost finished, I'm adding some final obstacles and challenges in now. The music was created using Nanoloop (GBA) and the sound effects on LSDJ (GB). Shame I ran out of time to make those better, but they're okay. Really happy with how it looks, even if the game is pretty straightforward.

Obligatory gif:

Oh, and here's the game if you want a little play around. This version doesn't have enemies or obstacles in it but you get the idea. Desktop browser only.
