I only have 2 problems with this game:
1, The shop only lets you buy one item/weapon at a time, there comes a point where I have a lot of cash and I cannot even use all of it because of this limitation.
2, the projectile throwing enemies can still attack while doing the death animation, resulting in a spike coming almost out of nowhere.
EDIT: Also I could walk through a wall and go out of bounds once. Rare but strange nonetheless.
All that said this is a great game. I like roguelikes and if it wasn't because of these issues I could replay this game all day long. This has the potential to become a full steam release if you fix these issues and add more content.
