In ver3.1, the box did not charge on its own, possibly because of optimization issues, and only clicking or some other methods will charge the box which greatly reduces difficulty. This was quickly fixed. The game has no winning conditions. Maxing out all stickmen and monster upgrades and collecting as much cash as possible is considered to be the aim. The upper limit for money is currently $999,999,999,999,999,999. (1018-1) This was much lower, at $9999999, before ver 1.9. (107-1) The game has dimensions of 512×384.
