I have taken a liking to a game series called "Thing-Thing."
I've played all the games before, but I started again.
I never finished Thing-Thing 4, so I started again, but there is this weird and annoying glitch that prevents my gameplay.
Either a few seconds, or, when the level is almost finished, my avatar... uh...
Well, he vanishes off the screen.
Not just invisible, but the camera jerks back to the beginning, and I see his gun sticking through the wall as he falls, then, when the bottom floor of the level (You know how Thing-Thing 4 has some platform elements) has has been passed, the camera stops, but my dude just keeps falling.
When I click, the screen shudders, and my ammo count goes down, but those are the last signs of him.
I've tried different sites, hacked and original versions, and even two different computers! (Both are XP, which might have something to do with it, I suppose)
But can someone PLEASE help me! I REALLY want to finish this game!
