Super fun. Impossible even to get the first star, must have tried like 112 times, but still has that "one more go" addictive feel to it.

Release date: 22 December 2017
Thanks. Yes, Sigi is coming to Steam (and Xbox One), with achievements and leaderboards, hopefully around Xmas.
Super addictive game, this will drive you nuts! Excellent gameplay.
Had to give up though at level 8 after trying like 150 times.
