Apparently no one knows this game, so I'll solve so that the game can continue. The screenshots were from a game called El Dorado 2 (a nice RPG-maker game).
Round is open, whoever wants may post the next game
Looks interesting, thanks for the suggestion. But it seems to be available only in German or from German websites? That might explain why noone guessed it. ;)
That's right. That might explain it. I thought it had been translated, but after checking now it seems that I was wrong. Anyway, have fun with it. If you like it you should also try "Die Reise ins All" by the same author (realtroll). Which is a good steampunk RPG.
