this is good game and all, but I think you might need to add a cancel button whenever you purchase a tree, machine, farm, dungeon, etc. I had this problem when I was playing and didn't have enough space you could also add a sell button in case you to make more space

But anyways this is still good

i agree you should give me money

cool

It is a very simple game for simple people. I very much like the sound effect when you buy for more coins per second. And I enjoyed it
Edit: I just found out it saves your game so im gonna make money till i die!

Fun
