Misunderstood the game at first and was trying to "buy" for a low price and sell" for a high price :)
Once I understand, I was supposed to be being a good system and not make money buying/selling, I did fine.
I played three days but got a little repetitive, some different mechanism could have stretched this one out - maybe letting the player drag and drop to organize or something, not sure
Lastly, sound sound/music would have helped too
Thanks for submitting though
