Good game to play daily for few minutes. Doesn't push ads to players, it is optional. Gacha and 'cat food' does seem expensive, so doing 100% collection of cats will require real money if one wishes to go down that route. However, some degree of 'Cat food' is obtainable for free players with doing missions, and can have a decent progression speed. Constant updates, respond to users, compensation for game issues, etc; Devs are really awesome. .. all good except searching monthly mob is tedious
