Needs some work, but not bad.
The game plays fairly well, and I figured out how to do virtually everything without any help (have no idea how to do the hex codes, so I just jumped through the lasers to get everything but the gold pile behind bars), but there are a few problems. The radar needs a little more distance to be useful. I generally get shot before the red blip ever shows up, regardless of speed. Jumping isn't easy to get right (probably the reasoning behind the persistent medal), and you can't shoot while crawling. I tried doing so to get some kind of protection from being a smaller target and got killed quickly.
The fact that so many people struggled with how some of the logic worked in the game is funny. It's pretty obvious what the code is on the keypad after using the donuts if you think about it. Who stops in the middle of a code to eat something? You also got some really good distance with the gun if you lined up your shots when enemies just get into view, though there's apparantly no way to enter most rooms without alerting everyone inside.
Anyways, I'm also posting because I beat your score fair and square. I can't see how Fooliolo's score couldn't be fake, unless that gold pile is just an outrageous boost.
