Good Game, for the most part. The main issues are two things.
1. Jumping and movement don't transfer between scenes making some of the wall jump sections really difficult to get past when they switch scenes.
2. Coyote time is non-existing in this game. To put it briefly Coyote time is when you run off a platform and you can still jump after a second of time passes. Like in the old Roadrunner cartoons where the Coyote stays in midair for a few seconds before he looks down and then starts falling.
Also, something that would be nice also would be a few different modes.
Easy: No health, just gotta worry about the pleasure meter and pleasure meter only
Normal: How the game was intended
Hard/Impossible?: No refills on health and no pleasure removing pills, you have to make it through the game with whatever you got, might be impossible so another option could be no pleasure removing pills, only a few sections where pleasure is reset to 0 so you can pass some zones but you might be able to get away with no healing of any kind in this mode
these are just some ideas but they would be nice
(edit): Just saw in an older comment how you no longer have the project files. Just wanted to say I hope you can find some way to recover them. I might be able to help though; what game engine did you use to make the game? I might be able to decompile the game and then give you instructions on how to decompile the game and then you can update it. If you don't want to though that's just fine.
