Well...
There are 2 things about this game that ruined it for me.
1st; No way to upgrade your ship. Armor or shielding upgrades would have helped out alot. This game is actually hard even when you know what you are doing.
2nd; the 2nd boss is pretty much impossible. Period. I don't want to here how you guys think the game is way to easy, because it isn't. I can't beat the 2nd boss. Her spiralling attack pattern is impossible to predict and impossible to dodge. You pretty much need the luck of the gods to get past her.
The concept is cool and it was fun at least in the beginning. But that second boss killed the game for me. I won't come back to it again, and I don't recommend this game.
