interesting tension here, as the various constraints of the game really force you to jerk off in a specific way if you want to win and don't want to fill up the red bar.
my best run so far did involve the red bar going up once, so maybe there is some value in it? i can't tell for sure if it jacks you off faster than you can go manually.
keeping track of what all the different bars do is a bit tricky but i think i got the hang of it. thank you for providing context in the game description!
nitpick: the game is really small on my monitor's default resolution, so i kinda had to change my resolution to play it. i think this game would be perfectly fine resizing with a fixed aspect ratio, e.g. with it blackboxed inside a resizable window.
