Hi,
Here's a video that shows the relatively early Shoot 'Em Up Engine I am building for the CX16. In the engine, enemies are scripted, and the enemies are active objects with program counters, stack pointers, local memory, etc. all in a cooperative multi-tasking environment. There's still quite some way to go before I am ready to make an actual game with this, but so far, it's looking really promising. Iteration time for building things is very quick and I love the idea of giving designers, musicians and artists the tools to do what they do (partly because I can't do that stuff ;)
Thank you
Stefan
