Honestly, what's the point of arguing over how precise the colors are? It's a game, it's not meant to be exactly the same as real life. If you're so intent on things being realistic, go argue on the comments of desktop tower defense.
Btw, I thought the game was fun, even though it didn't hold my interest for too long.
It would be fun if there was some warning of where the stars would appear on the next level. I died because a death star appeared me when the level switched.
It's fun, but it's too easy. Once I found the planet that sold weapons for 2000, I made over $1,000,000,000 in about five minutes. If trading was made trickier, and especially if there were set missions to complete or a clear objectives, this could be an amazing game.
Fun at first, but becomes so frustrating that it's not even worth playing. If they're going to have a game with permadeath, they should let you save without making you join their site.
