I dunno what crack the other reviewers are smoking
It's not easy. It's retarded difficult, but more than that, it's unintuitive. Generally when there's a magnetic element to the game, it's a 360 degree shooter, where the enemies come from all directions and there's less bullet hell to worry about. Difference being, in a top-down shooter it's always better to be at the bottom of the screen, but in this game you can't; you don't earn any money, you have to go and wander up near where the enemies come from. That's a horrible idea in a top-down shooter. If you kill something, either the money should float down to the bottom of the screen or it should automatically be collected as the enemies die. That's how things work in top-down shooters for a reason: It's the best way to do it. As it stands, you're forcing the player into a more dangerous situation where he will die. You're encouraging scumming, just purposely dying over and over again and scrounging up what little he can get before he kicks the bucket so he can afford more upgrades and survive that much longer and earn that much more, without ever really caring if he makes it to the next level. That's bad game design. The main gun is all but useless in everything except maybe boss fights, but even then the minions might be more effective there.
