...really? Ten levels of progressively increasing difficulty, and all I have to show for it is a sore mouse-holding hand? You've made some crappy games in the past, but at least most of those had a splash screen or some sort of ending cutscene. All you get here is a brief "game complete" and a black screen asking you to play again.
It doesn't help that some of the hitboxes for the portals were wildly inconsistent. At some points, I was forced to see the "firing sequence" animation through to the end after screwing a girl, and other times I could just click right to another after the "Bingo!" popped up... and sometimes, on rare occasions, I would be frantically clicking on a portal while idle and nothing would happen.
But... fuck it. You get this many stars just because you had an interesting concept to work with. If it wasn't as frantic and engaging as it ended up being, I would've quit two levels in.
