This was a very interesting game - mix of mine sweeper and dungeon! I had fun and was able to complete all the 4 free levels. I think the balance is really good since most of the times I had to be very strategic on what enemies to defeat first/when to use my potions. The only thing I would suggest is if a player is obviously going to die (i.e. I have 5 health and I click on a 7 HP monster that has been revealed) to just pop up a warning instead of allowing the player to knowingly kill themselves (most likely due to misclick while they are trying to learn the game). This will help players learn the game faster because this will remove hesitation when clicking on useful clickable tiles (such as talisman that helps you) instead of being afraid to click on the wrong thing just because player is unsure what it does.
