I am impressed that you managed to put together a complicated game in under a week. That is really cool!
I thought I was going to die against the stupid skeleton until I decided to just "swing randomly" with my last conscious character.
I didn't know how Looting works, I tried pressing L and nothing seemed to happen. Maybe I missed something.
I would have to side with TheGrumpyGameDev and Chekisteg's comment, this game can get VERY VERY complicated and that could create a lot of friction for beginners.
The "party is lost" mechanic is really confusing and I just don't think it works here. I'm not saying that it couldn't work, it could have been implemented better. I think the easiest way to put it is that you simply overdid it.
There is only two things this game needs to make it better,
1: More improved level design. The catacombs are too difficult. It's not immediately obvious how you get lost in them. This would make the party is lost mechanic more tolerable. Make it feel like your making progress more often than your going around in circles. I know there were times were I knew I was lost but seriously, I was still contemplating that the game was bugged more than anything else.
2: An Objective: Make it clear what you are looking for. Too be honest, I'm not even sure how you could implement this, maybe you could start with the door with a password. I thought after I opened it I would get further. Instead I found an alternate path and went in a complete circle. Long story short, I never beat the game.
Well, that's all I have to say but still, this is a very impressive game with a lot of mechanics. See ya!
