This returns to version of V1.01.101. The one after V1.01.101 was purely for testing if the Steam API is working properly for the added Steam Achievements.
Steam Achievements are now integrated!
- Unlocks are saved and will appear on your Steam profile.
- If you don't see the in-game popup notification, make sure "Enable the Steam Overlay while in-game" is checked in your game's Steam Properties (right-click game → Properties → General tab).
- Achievements still work even without the popup — it's just visual feedback.
