Heeeeey! Nice mechanic. It was fun to go against the clock. I like the battle system, nice skills and nice setup with shields and stuff.
My only complaint is that I dont think you can beat the last boss without one health potion(forgot the name). I was out of them so I backtracked to the the vending machine. But what if I dont have any money left=? Or what if the player didn't discovered the vending machine?]
They would be softlocked. Otherwise, very neat entry!
