I’m sorry, but I think I’m gonna have to be pretty harsh with my criticism.
I won’t comment on the gameplay being basically a copy of many other games, it’s up to you to make whatever kind of game you want.
The gameplay doesn’t work. I think you meant to play an animation when clicking the pickaxe, but it doesn’t seem to work (and if there isn’t any, then the ores are straight up almost unreachable).
There are two shop buildings but only one works.
The reward chests do not have any kind of indication on what they do (are they daily rewards? Do you need VIP/Premium to get them?).
The economy is way too unbalanced and would take too much time to grind.
The GUI is low effort and inconsistent.
