Much too hard
This game is hard to the point of not being fun. The map only has like five levels and it seems like its trying to make up for this by making you retry level after level in order to get cash to upgrade your ship. It doesnt tell you what any of the upgrades do either which further frustrates the player. There are numerous enemies right from the first level that can kill you very fast or in one hit, making this too frustrating to bother with.
