This game seriously should get a lot more attention. The gameplay is simple to understand but also addicting, and it is a good balance between AFK and actively playing. However, recently an issue has popped up with the game randomly crashing, which gets very annoying, having to reopen the game again.

Great game, Reminds me of Howls Moving Castle which is my all time favourite movie. Been having issues since the new 2 year update where it download the file but it stays on that screen and doesn’t proceed to the game. Tried to redownload multiple times, then phone off and on and install latest iOS update but still no fix

Underrated game but slight performance issues

I really enjoy this game especially the art style however I have been playing and receive frequent freezing of the game even on the minimum graphics settings. I am using an iPhone 11 so may be a phone issue but I would love to see this bug fixed.

Severe overheating, not very well optimised and if you don’t want to ruin your battery I suggest only playing 20-30 minutes at a time.
