This is a beautiful, well designed game thats ideal for killing time. Contrary to the complaints of other reviewers, I dont think the controls are too cumbersome. You are a Japanese university student named Sara(???) who is tasked to assault the adorable "Ojipockles" (old man fairies) who occupy her small flat with bottle of "fairy water", whereupon they will burst into hearts, which eventually allow you to level up and assault more Ojipockles in different outfits. Yeah, I dont get it either. This game is super addicting but I wish there were slightly more plot development here. Because the prologue was handled so beautifully, I had really been looking forward to more cutscenes with dialogue or something. After getting to level 13 of 36, Im starting to feel like theres arent many incentives to look forward to beyond viewing new Oji designs. The gameplay is also so simple that Id actually like it if it more challenges were thrown at me. Theres really no way to "lose," or even be set back a little. No enemies, no time limits, no chasing. All that said, this is still pretty incredible for a free mobile game. The concept is fun, entertaining and its visually pleasing.
