I played 5-6 times (in most of them I died on the last monster or near him) before my first and the only victory.
+ incredibly engaging
+ enjoyable
+ really good sfx
+ nice-looking graphics
Game is really replayability, there are a lot of items/mechanics, so you can play every time in different ways, every run is unique.
I think there are few little bugs, but they are not ruining the game.
I didn't remember what gold was for, but when I won, I realised that it is for unlocking new champs/volunteers, so I can play more and more...
Overall, I played about 1,5h and unlocked all heros.
PS I joined Steam Playtest
