Came back after a few years to see if the game improved. It can be almost unplayable if you don't prioritize unit grind and time rift. It seems they made some things less of a hassle and added more sweeps which let's you complete tedious tasks and the floating castle mechanic that can get you grinding materials to make things less painful. Would love to give this game a good score, but this is an expensive game that caters to very small niche crowd.
