1.2c Hotfix - Fix freeze happening for some players

Some players reported the game freezing at the end of a puzzle, but progress was still saved.

We've updated Unity version, which now also include a security fix, and optimize some code to free up some memory, it apparently fixed the freeze for players. As a bonus, puzzles loading should be smoother now!

If you have any issue, please send a mail to squeakross@alblune.com, or get in touch on discord at discord.gg/alblune

Thanks!
