There's no point honestly. Most of this dev's games are unfinished messes. For example, they have another game called Zombiepunk.
@Bedo13 even has a mod for it. That game is unfinished as well. After a certain point of repetitive farming you'll get a Coming Soon message. It's so frustrating.
These are just low effort cash grabs. So play it for a while and just move on to other games. That's what I do.
