Before I started playing with Python + Pygame on Linux, I was using Game Maker for Windows ... Yes, this is mostly a PS3/Linux oriented forum, but I haven't found anything like Game Maker for Windows that will run on the PS3 (and it doesn't run on Windows via QEMU, either, due to the video card requirement). Maybe one of the older versions would work?
Where to get it (a "lite" free version is available):
