I'd play in fullscreen. Click on the circle. Keep on clicking on the circle. Buy some buildings and a few upgrades, and then keep clicking. Eventually reset for some points, and gain money faster. You unlock upgrades by unlocking achievements. Secret achievements require you to do random stuff to unlock them. All upgrades that cost 0 coins are from secret achievements. Upgrade descriptions: +1 Click Increases click worth by one. +10% Clk. Increases click production by 10% of building production. #x10: multiplies building production by specified amount. Allx2: multiplies all building production by specified amount. +1%/Bld. Gives one percent extra production bonus to all buildings per building. (Essentially just a really good upgrade). +1/point: gives an extra 1% production bonus per point you have from resetting. +10Mon.: Gives ten coins. Resetting is super beneficial. I'd reset at around 100, as you can get some real momentum from there, but feel free to reset whenever! The game starts to lag really bad if you get too much money so... good luck with that. Other than that, have fun! If you have any questions or thoughts comment below!
Thanks to: @ijsquires for the number reducing system and game testing. ...and other than that it was just me. And don't worry, I'm working on new platformers too. Changelog: July 2nd: released! June 14th: finished working on "Again.", and started this.
