Was really fun to play a bullet hell, mmo, but lacked active advertising by devs.
Then they took it down for an 'update' and it never came back.
Last I've heard is that they kept promising to bring the game back to mobile (was on steam now) but they refused to release android and ios separately (either ios or playstore denied them) and they refused to release an Apk version that could have easily gotten around that so they could have kept an active player base.
Games dead now.
