On Arch Linux you could get the libnotify.so.4 error (with 32 bits packages), by installing this package from AUR it resolve the issue : https://aur.archlinux.org/packages/lib32-libnotify....
Maybe a 64bits version can avoid that. Otherwise great game, a bit too small to play on PC though! :D

Besides AUR's lib32-libnotify there are some other packages that need to be installed too:
lib32-gtk3 (removing lib32-gtk3-classic)
lib32-nss
lib32-gconf
I think that's enough to pull the dependency chain necessary for running this game. If not, just read console output then ask for help. :)
