@Lagressa - Yea I noticed that too, but it really helped me in terms of things that gave tons of resistance or specific spells. For some reason I could get the extra armor about 1/2 the time but I never did get the extra damage to work.
To equip more than 1 sword/helmet/armor at the same time equip a ring and then drag that ring onto something in your inventory and that piece of equipment will now be in your ring slot. This is really helpful when you have 2 helmets with really great stats of if you want to equip 2 or 3 swords to increase your damage. + this so others can see!
To Beat the final boss easily: Fill your back 2 rows with Rockets, fill the rest of the screen with Lasers. Fill in any holes with bomb modules and during the game use your bombs. + this so people can see it.
