Most of the time spent on graphics – new sprites for the lumberjack and the indians, with two-frame animations, and a new bg. Nothing exciting, but just to have the legs actually moving while people walk gives a completely new feel for the game.

Oh, and then there is blood – those bloody indians now bleed and get smashed by trees!

From the programming side it was pretty much  just tweaking and fixing stuff for a smoother experience. You can play this version at www.cin.ufpe.br/~jhcp/ld25/v04
