Every score over 2900 is definitely impossible so they must have cheated or exploited some bug. I actually don't think anyone could get more than 2870 actually in normal conditions (who knows what bugs can those games generate on some pcs?).
Pseudo, I'm not that stupid to not notice/get that pretty trivial clue. Anyway I still think that first skull is misplaced; that's because it is the only one I see from top, so if I follow the advice to avoid the vertical where that skull is placed, instead than being awarded, I'm actually punished since I fall directly into the lava. Well, I know that's different for you since you're the developer and you know where the column are placed; that doesn't mean it should be unfair for first time players.
