(Happy new year!)
A new version of BOOM: Remake is out: 1.5.1.
This is a minor release fixing game saving that would fail when the saves directory is missing (thanks Mark for reporting it!).
Moreover, for stability reasons, I gave up on MinGW and started building the game with MSVC on Windows, since it now properly supports C++14 - which wasn’t the case when I started Lifish.
You can find the new version at the download page.
