Great game! 5/5. One suggestion would be to allow surviors to level up after completing X number of missions. The higher the rank the lower the risk for missions.
Unless you really want people to quit playing the game, I'd suggest that you dont place essentially unbeatable creatures in chests early in the game. I've been killed 3 times now by this stupid trick and there is nothing fun or entertaining about it. A level 20 griffin against my level 12 warriors - wonder how that is going to turn out.
Need to be able to reset upgrades. At the end all you want are tanks and support but you've wasted your upgrades on soldiers. I'd restart but the early levels aren't that fun.
Whether you can clear the dungeon in 25 turns or less seems to be entirely dependant on the random layout of the starting tiles in the mid to lower levels, which is lame.
Pretty good game. Kind of lame that the epic yeti was the only character that ever damaged by castle. Accordingly castle upgrades serve no real purpose.
Sucks that you need 17 points to unlock all amateur songs, which means you need golds and silvers on every other song. And why is there only one easy song? The medium badge is far too much work (and repetative) for people that don't enjoy this type of game :(
