I love the atmosphere, I love the music. I played it solo only for now and it's fun, it's surely awesome to play locally with friends.
While I'm usually not fan of difficult games, this one is special in its design, with infinite retries, so I went to unlock all levels without rage quitting :)
I'm also a fan of Pryapisme (real life friends, in case you wonder how I got a key for free), who composed the music specially for the game. And it works so well in my humble opinion :)
TL;DR a well polished game with its own identity and atmosphere, with the great addition of a great soundtrack and a decent price...
