I've uploaded the source for a simple block stacking game I wrote years ago. It uses one set of external files for the bitmap font but otherwise everything is done using shapes.
also... would anyone be interested in helping to complete making a Cannon Fodder style game I started a long time ago? there's a PC version writing using Blitz3D (which is free to download) and a very partially done conversion to B4A that needs finishing. I'll start a new thread for it if anyone wants to get involved.
