i found an awesome glitch. on level xv or 15 if you start to play on easy and click the white flag then surrender right away you get 12500 gold, the same for hard except you get 30,000 gold. you can just keep starting and quitting this level to gain millions of gold. this does not work if you press P and quit, you MUST click the white flag and surrender.
man i beat lvl 1-9 first try no probs. level 10 i've been at for 20 minutes and now i give up. hate to down rank the game for this but it must be done.
i ended up getting this game after playing it here. if you liked the flash demo you really will like the full game, and it's only ten bucks. also if you think the last level on this game is hard you aint seen nothin yet.
i put on a pair of glasses i had lying around too. cool idea. i hate the after effect though. takes awhile for my eyes to see the same color temp again. if people down rank this for being a lame game they're stupid cause this is obviously more about proof of concept than anything. 5/5
