Just tried out this game and it was a lot of fun! It is very simple and to the point in terms of story/overall mechanics which makes this very easy to pick up and run with it. Combat I found to be quite fun and the pace just about right. Being able to swap out different skill attacks was nice, so matching elements with the floor was a breeze, though it did get a bit repetitive since the elements seemed to change often enough. The equipment that you get throughout the dungeon more often than not is worse than what is already equipped making a lot of it perhaps a bit pointless - might as well just give extra gold instead! The dungeon levels were a bit lackluster - there was almost no point to being able to walk around at all since each floor was the same - one or two items in chests/crates and whatever monster is blocking the ladder downward. More variety here would have been awesome :)
Overall the atmosphere and presentation was great. This is the sort of game that if worked on, extended, and polished further it could probably go up for sale on Steam. Great work!
