Simple and enjoyable game but ruined by greed like most gatchas out. I had it at 3 stars even with its issues and they kept deleting reviews. Gaining gems after you beat story seems to slow down significantly. You can beat the story in like a week or 2. It'll take 5 weeks for a f2p to save for multi. Pity is around over 10,000 gems seeing as I did 5500 gems on banner and did not get one unit or memory. If you like mha and patience then I recommend bit to everyone else no just save your time.
