0.9.13.0 - Save Slots, Fix Performance Regression!
New save slot functionality - save slots! You can now freely switch between 4 save slots (on the settings tab), and this is part of the groundwork for, having a new version of the game in the future, which could have differences in gameplay (in a separate save slot).
Upgrade to golang 1.16.5
Upgrade to ebiten engine v2.1.
Fix a performance regression that was on the prior release on windows (some old dependencies got mixed into that build, sorry!).
Fix bugs related to tutorial UI showing up in duplicate in some situations or otherwise misbehaving where you load a save (such as importing a save, also affected switching save slots).
Fix bug with preserving a few older backups of your save on disk (backups weren't always happening the way they were supposed to).
