Thanks for the tip with the furnace. I tried the game again, and now I feel so dumb xD I was standing on the wrong side of the furnace :O and tried to put the stuff into the output slot. I do think that the time on each planet is a bit short, I was not able to get to iron when playing legit. When cheesing the hell out of it, i got to the space gun, and it looked really good. I was not able to win though, (which is not a bad thing, because I bugged it) Overall the rest of the game was great, the inventory system works well most of the time, theres only the problem, when the rocked or a table is behind the invetory, you cant put anything in the slots.
