I played your fixed version. I like the game; it's a bit difficult, which I like. I have some suggestions/issues to list:
- different primary weapons that you can unlock or find for variety; not sure if this is already in the game, I'm bad and died several times on level 2
- it's hard to pick up items that are on a teleporter unless you're not standing on the teleporter
some type of indicator that you're getting money from killing monsters(I just noticed the coin animation, maybe a sound too?)- auto-pick up mana/health potions, I don't see a reason that you need to click a button to pick them up
- spells should say how much mana they consume unless that's an intentional design decision
- the map should have an icon of where you're at on it
- have those blood particles when shooting monster go out in the direction that you shoot, would look better
