Graphics are hardware accelerated with GLES2 and JIT on ARM is included.
On the Game Menu "m" or 'space", try "Alpha Hack" and/or remove "Buffered rendering" and/or "Autoframeskip" for better result. And remove MipMap option, works better without it.
Notes that this is an app targeted to Android market, with touch devices. So GUI is touch oriented (click and drag to move, long click to validate).
