Barely bought any upgrades and got all badges. The sad part is, this was a cake walk compared to TOUHOU PROJECT http://touhou.wikia(DOT)com/wiki/Touhou_Wiki a hard shooter which makes this seem like it is for babies. Anyway, The guy who talks to you was poorly drawn and therefor, this game gets 4 drunken monkeys out of 5.
that was easy, do nightmare mode for demons and use rockets when they level up
always put turrets in the middle whenever you get more ammo
keep going around collecting turret ammo and using rockets and you'll get it
