Hello friends, i have BiT Evolution in my Steam Account and i cannot play, i clicked to start and appear "steam failed to start game unknown error"... my computer is: 2gb ram, g-force 210 500gb hd Windows XP is because my Windows is XP?

The final boss is bugged for me. The boss doesn't spawn in the ''final'' phase and when I jump the game triggers that I bet him. Can't unlock the achievement or unlock the challenge mode...

I've reached the end, but failed the Level. Bug? Or is it only possible to succeed the level, when the boss is in front of you? :D How i failed: https://www.youtube.com/watch?v=OUWxVUrSLi4 How i succeed: https://www.youtube.com/watch?v=yhaLidrpaho

I see a couple user reviews with 3-5 hours of playtime but I can't find anyone mentioning how long a full playthrough usually takes. It's not that I won't buy a short game of this price. I'm just curious.

So I was playing this (and my son loves watching me play) and we both found a 21st bit in level 2-7. Is this intentional or is this a bug of some sort?
