I had trouble getting this to work even on PPSSPP (inputs weren't working on my computer for some reason?!) and it would crash on my PSP-1000 and Go, but luckily my brother (Skleembof) got it working on his, so I went over there to finally try it out just in time before voting ends!
The game was fun! I had actually never played an FPS game on PSP before, but using the L/R triggers to control the camera turned out to be intuitive. The game's slippery physics take a while to get used to, but I think that adds to the challenge/fun of it. Graphics were nice, and I especially liked the music.
I never made it all the way to the top though. I fell down too many times and eventually gave up :(
The idea of bugs giving you power-ups is cool, but I think they run out too quickly. It's not immediately obvious what they do sometimes, and by the time you figure it out it probably ran out.
But anyways, great submission!
