TBH I refunded the game after 1.5h, but the devs deserve some love for this gem. If you have ever played a mobile gacha game and wished all the mechanics were unlocked by playing the game and not with money. Then this game is for you! Seriously. The whole time I played I was thankful I was not being drowned with calls for my CC. I refunded because i didn't see a huge amount of strategy, which I prefer in my idles, I did and do see a lot of potential and I support devs not trying to rake their fans over the coals.
EDIT: I am glad I changed my mind. Slow burner, but surprisingly fun and cute game that does offer more depth as you play and I am curious to see where it goes.
