It was kind of smooth the first time I played it, with a couple of lag spikes here and there but that might just be my crappy old laptop's fault (I lag the most when the game zooms in when Tim gets near the mansion, though, if you were maybe even the least bit interested). The second time I played through, though, to try and get all the medals, I glitched after encountering some lag while trying to go across the street with Greg's black and white T-Shirt, resulting in jumping all the way to the ending and getting the medal "Here It Comes!". I mean, although that was a free medal right there, I'd have to take points off for the glitch. And during my third playthrough, I'm not sure whether it was intended or not, after putting one of Greg's T-Shirts into the washer (the black and green one) and washing it with 'Die, Dirt, Die!' plus warm, the T-Shirt inflated like a balloon and then popped, followed by several items appearing in Tim's hands and disappearing really quick. Then, once I had to go back to Greg for another T-Shirt, he had the same shirt still on him and available for selection! I've still yet to get all the medals, so I'll most likely encounter more glitches, or what seems like glitches to me.
I liked the storyboard, the music, and was a pretty funny game, overall. The art could've been better, but I feel as though the game just wouldn't feel the same if the art were to be more detailed. I just can't imagine it, you could say. I feel perfectly fine playing through this game with the current artwork and animation it has. The music sounded repetitive, but not to the point where I would just want to pull my hair out. I actually quite enjoyed the music. It sounds natural, even if it's just the same thing playing over and over again.
