People are just trying their best to rip what they can but I know its not a very easy process because of the complicated approval feature here and that is why not many people like contributing here all the time but this site should deserve serious improvement to make submitting easier and faster for most of us sprite ripping folks honestly. Calling anyone here selfish is rude and disrespectful to the community in general here. This boulder can be pushed around, but it is quite buggy in this build. Of course the makers of this game didn't have their loyal customers and fans alike ripping their stuff in mind but at least if they could have used the background decoy as individual sprites instead of part of the background would be heck of a lot easier for fellow sprite rippers to divide the trees, bushes, rocks, the ufos, and so on in organized categories instead of like I said part of said Also think twice before you say something to people who are not. Although its sprite can be found in the final game via debug mode, it cannot be placed. This is just too bad and while its not really the fault of the rippers here, I can only blame the ones who did the sprites for this game.
