For the 48 Charity mini LD, I just submitted my game called “Crazy Kart Flying”. A bit going passed the limits and using 3D, but I did
use the NES Palette and limited movement along the x and y axis. Programs used are Unity 3D and Paint.net.
Only 2 levels, but I like the idea and I’m extending on it so expect a 3rd level (hint: a “special” level )
Page to play would be here: http://www.charitygamejam.com/
Shoudl be able to find it.
