love it!
still there is some ways to improve:
- as already mentioned, don't stop when not focused.
- store data (lost data on reload)
- the collecting minigames are there just for the very early (could be reused later on)
- z in the mining game is pretty tricky for qwertz keyboards ;) (could be exchanged to t)
- amount of resources gathered while playing minigame could be displayed to give the player an reward
- clients needs to be +1 otherwise one of the worker will stand still all the time in the later game
- some kind of 'error message' saying resource xyz is missing to finish order
- at the moment chrome is blocking 2 thrid party cookies (maybe not necessary)
keep up the great work!!!
