Good idea, this enlivening presentation, too bad the technical demo preamble only shows color changes and movements and doesn't show what the gba has up its sleeve ^^.
Viewing post in GBADEV Containers jam comments
Thanks! I somewhat ran out of time, but still wanted to join the Jam. It's a little bit of a meta-entry as a lot of the time was spent on the containerfiles, reading what was available, and experimental gimp -> butano bmp export rather than the rom itself. I'd restored my gba for fun and only discovered the Jam by accident, I was super impressed by how accessible making stuff is, and how elaborate the community has managed to go with full games compared to other platforms :)
