The game seems like it has a lot of potential, but it needs a lot of fixing!

The turns don't seem to time correctly, since I went into a floor and the monsters all ganged against me and moved constantly and I couldn't move or act at all.
Also, I'm not sure why it is, but sometimes, the monsters just do a LOT of damage even in the first floor. Even using a big green potion (which I suppose it's regeneration) I was killed by 2 enemies that chomped away 15 HP in 1 turn and I just did 25% damage to them each attack.
Also, are there spells in the game? Not sure what the mana is for.
