Fun but very difficult

First 1 level was but the levels are very long and there is no check point or option to be revived. Limited lives is annoying and stops me from playing. Other levels beyond level 3 are way too fast and very very hard to beat or complete even 50%. Continues to crash mid game. Updates and revision needed immediately for game to still be popular and worth playing

Lssss about Rolling Sky, v1.2.4
