I thought I'd try and create a flash game that could be played on a PSP, and this is the result!
There's not much room to work in on a PSP, (the screen is small, the memory tight) and any full screen movement slows the flash down to a crawl, so you have to choose the type of game carefully if it's going to be any good.
So this is an update of a classic game (Bomb Run, Bomber Baron), optimised as much as I possibly could (only 21k!), using pixel graphics to keep the size small and the redraw as smooth as possible. And I think it works pretty well - but you can be the judge.
