Here, as mentioned, the minor update! xD

🥺👉👈 Took the opportunity to put supporter names on the credits (that I've forgot on main update, sorry ;u; 💛)

Devlog

• Main Menu: Christmas themed main menu.
• Translation: Portuguese and Spanish translations are mostly up to date.
• Bug Fix Attempt: added a code to try to fix an incompatibility issue with loading saves from previous versions, which seems to only occur on Android devices.
• Bug Fix: socializing at swimming class no longer enters an infinite loop when started in a minute other than 0 or 30.
