Hi there! I working on an endless space arcade "Space Trip" - anyone can check the current progress on Scirra Arcade. So, I've read & complied already all optimization guides, but anyway met some performance issues especially on mobiles, but don't really understand why. Resolution is 1080x1920 All obstacles in game (as well stars on the background) moves via 8-direction behaviour and will be destroyed outside layout. There no particles objects are used, and even if I disable all obstacles and effects fps on mobile still is 20-30.... It's the first time when I got such trouble... If you have some ideas about, or any other feedback - it will be very appreciated!
