It's nice mindless game to waste your time on while you think about which game you really want to play. Loot Hero gets boring pretty fast. I got all the achievements in less than 4 hours.
With that said I should point out that the sound and music is pretty good.
Graphics is alright. I liked the Monsters and the Shop buildings.
The game doesn't seem to have any bugs that I have noticed myself.
It wouldn't be a game I would pay more than 3 dollars for. So if it's on sale and you want a game that doesn't require skill or much thought, this may be the game for you.
