Definitely give the game go. The idea of every hero having one "passive" and one skill is quite nice, and adds a certain replayability, but the game needs some tweaking here and there still. I started out with "The Stein", whose HP regen makes you practically invunerable unless you get swarmed, which doesn't happen pretty much at all for the first few levels. Before I knew it the game felt repetitive, mostly because I couldn't really die and got really good items from the very beginning, making my hero pretty OP.
As per bugs and suggestions:
--> Give a larger inventory view and/or make the little arrows scrolling through it actually work. It gets pretty hard keeping track of your inventory when you are holding on to items for different epic sets, and the lack of scrolling makes it impossible to sell off stuff if you don't sell some of your epic items too at times.
--> Reduce the drop rates for epic items from mobs/shop. Through the game I bought many 'random' items from shop, and all but 2 of them were epic items. There's no point in having normal and rare items if you get your hands on Epic items from lvl 1! It'd be more challenging to have limits to the quality of drops & shop items so you don't get too strong too fast.
--> Possibly add a minimap or zoom? It's easy to find yourself running circles through the different rooms, cause the only thing guiding you is your sense of direction.
All in all, you get a 4/5. This is a nice little game, however there is some room for improvement. :)
