The glitch is just fun... You don't have to hold enter, just press it a few times and you can upgrade the Tack Tower to hypersonic and you only have like -2000 money so you earn it back and can just get wahtever you want.
Flame, are you serious? Pick up the money and sell your unused items. I was able to get to level 20 my first time playing and I bought almost every item (both weapons, all bows, all spells, and half of the armors).
shoot the tube on the roof. kill that guard.
when the walking guard is facing left, kill the other guard in the window. then when he's walking right, kill the other guard on that level. then shoot the walking guard. all that's left is the two on the roof. shoot the 2 cords. when the guard walks over (the one that was originally the middle), shoot him (there's a delay before he calls the alarm)
