I love the ragdoll Count; very cute.
I enjoyed the puzzle of figuring out what the best path was; initially I'd get stuck on a seemingly impossible path, only to realise that there was an alternative, so that was nice level design.
The game does strike me as a bit of a rage game, and it certainly brought that out in me, ha. I'm not sure if it was deliberate, but the bat is nigh-impossible to control, flying at insane speeds sometimes and barely moving at all at others. Perhaps part of the issue was also the controls? Having to have a hand on the mouse meant that I couldn't really mash the space bar as much as I wanted, which probably led to some of my lacklustre lifting power.
I got a bit too frustrated and quit before finishing level 4 or 5, but I had a good time when I managed to pull off a seemingly impossible task!
