Prehistorik Man is a caveman-themed platformer by French development studio Titus. It's colorful and enjoyable, and first time author magus gives you quite a tour of the game. Just make sure you don't start swinging a club at everything you see after watching it.
This run is 1 minute 24 seconds faster than the predecessor movie (http://tasvideos.org/2067M.html) due to general optimizations.
