As fun as this game was, it as really easy. The bosses didn't respawn, so you only get to fight it once. I beat the final boss with few upgrades, chain armor, the sword that comes after rusty, and an invinc potion. I feel like the bosses should be way harder so you have to get most of the upgrades and armor and weopans.
Wow. This game is very fun, but I do agree with @PrincessWilly that the AI isn't very good. There are many great concepts, that I may play IRL in the future.
Thanks!
