I can see the work you put into it! The game has potential, lots of mechanics are in place.
The inital walk to the mine could be even shorter for my taste (exposition through snappy dialogs was good I think), but once we're in the mine everything feels right.
On the level 3 I got unfortunately locked here (I couldn't move down,even without the warlock there) and the game from being very easy suddenly became very hard.

Maybe health potion drops could happen more often too.
Overall I like it!
