Pretty solid game. There are a few things I'm not fond of. The weapon and armor upgrades should just be straight upgrades, instead of taking up the usable item slot.
There are also several places where you can get stuck where the only option is to reload, particularly in the last dungeon, which is fairly confusing. There's several doors that have no clear way to open them and make getting around a mix of backtracking or reloading/dying. But I was able to get there in the end.
A really minor issue that should be fixed is being able to open the menu screen on the game over screen.
However, that stuff aside, I really liked this. Played it straight through and had a good time.
