I have lots of time this wek to spend doing psp stuff as I got the week off, Supersprint will be done at the same time as other projects as the framerate tricks im using and figuring out for current stuff will help make Supersprint work well. It looks like a simple game but with all that rotational maths going on and some AI it can really chug, Its getting there however and soon as I have a decent framerate and fully functional track expect a demo.
Creatures is coming along very nicely and most of the core engine is in place and running fairly smooth, further optimisations will continue to follow and now I have dynamic content loading sorted the levels will grow fast, the full game will definetely safely exceed the 2mb flash size limit :)
