Not a bad timekiller, but it has bad optimisation and monetization. Optimisation: in my experience easily overheats the phone, eats a lot of battery and, most importantly, lags a lot after some time playing. Probably a memory leak. As for monetization: yes, it doesn't force ads on you, but you get like 3-4 faster progress if you watch ads (which you get A LOT). The most important upgrades require 100-250 diamonds and you get 5 diamonds per 2 hrs (+ a little from progression and events).

Honestly, this is my new favourite mobile game for killing time. It can keep me occupied for ages. Yes it's simple, but there's always something to do. I'm on level 14 and I still enjoy playing. Progress can be slow but it makes it more rewarding when you finally level up or get the resources to level up furnaces, for example. The weekly challenges always help keep it more interesting.

The game is fun honestly. But it is the normal grindy gameplay with this one. My biggest issue is the clutter on the screen. Too many "buy this pack" and "subscribe with purchase" so it's hard to actually see what you're doing or who/what is around you. Just put all that clutter in the shop. It doesn't need to be on my screen while I'm trying to play. It doesn't make me want to buy it to get rid of it, it makes me want to stop playing.
