Unable to play on ip4 ios 7

It said that ios 6+ is required, my phone has ios 7 n its impossible to play. First, the beautiful graphic in the screenshots turns into lame 8bit. Then, some of the original scenes are skipped, I checked the walkthrough video online n see there is this scene at the beginning where he put the flower of her head, but there is no such scene in my game. Finally, and worst, the bg of the levels are pitch black, yes, black! Which means all the things u need to color disappear!!! Only the stuffs where u get the colors from remain visible!!! How can I advance in this BLIND COLORING GAME?!!! Dream?!!!
