Very nice - again! Also loved the momory cube. What I was really puzzled about was the "controller". Maybe it would help people like me if there were arrows on all four sides of the cross. But otherwise really nice design, good graphics, cool gameplay implementation.
Congratz on the release. You mention you change the branch - any chance of putting patches for your changes online? Maybe they are interesting enough to add to the engine so you don't have to modify it for your next game :-)
I fear that our modifications are of little use for the improvement of the engine. The modifications have mainly been about to remove things we did not need (even multitexturing). However, we've made a few changes in a try to optimize the engine for opengl.
Changes...
SColor - Changed the color order to avoid the vertex color conversion in the driver.
IVideoDriver - Splitted drawVertexPrimitiveList into three functions for faster rendering of objects sharing the same meshbuffer (not sure that the same can be done for Direct3D).
If there is interest, maybe we can provide a patch, at least for the ogl-es branch.
