The game is nice, but it tends to be pay to play, especially with time limited events. Each picture requires different amount of energy, but the energy bar stays at 100 no matter the level you are. I'm at a point where it costs 40-50⚡for a pic, so I can only do 2 with a full bar. I get no notification for full energy even though I accepted getting notified, and there's a lot of ad-watching involved. It's annoying when the only free option for more energy doesn't even give you enough to play.
