Gigachess v1.22 Update | Party Performance Tracking

Tracking of personal best scores per party, expanded gamepad controls and assorted fixes move Gigachess forward to v1.22 :)

  • Performance grades in Endless mode achieved with any party configuration on any difficulty are now backed up internally, with the best grade achieved by the selected party displaying at the bottom right of the party builder screen
  • Beating a previously achieved grade with a party causes a special pop-up to appear on the scoring screen at the end of the run
  • A bug with the performance grade calculation where the grade displayed at the end of an Endless run might change unexpectedly after a moment's wait fixed
  • Automatic vertical centering of the game window on launch has been adjusted slightly to be better positioned
  • The right analog stick on many USB gamepads can now be used to control the cursor in addition to the left analog stick
Added later via quiet patch (Dec 26, 2018 @ 10:20pm)
  • A secret method for resetting stat-based achievements added by player request
