While still fun, there are a couple major bugs in this game.
Notable ones that I noticed:
When you open your stash, items in it are treated as in your inventory. This includes charms and when you close the stash, the effect persists. Not only that, this happens each time the stash is opened, allowing for truly ungodly stats.
In a similar vein, the weapon Newgrounds Flesh Ripper (Lvl 72 Mace) seems to add its effect to your character every frame. With the large amount of bonuses, this gets very silly in very little time. I'm talking about having 200000 hit points after having it equipped for a couple of minutes silly. And you will never see them drop between your over 10000% dodge, block and damage reduction.
