Hmm. You're not supposed to be able to get over 170. Any idea how you did it? And what was your final total score?
My final score in Roomisode 2 was 175, and I did everything in the game as intended with no bugs or exploits.
I did another run of the part, but I was unable to replicate the overscore thing. I wonder if anyone else managed to do that, or if it was already fixed by now.
