Deltarune Chapter 2 release on a few hours more and you can get it completely for free on https://deltarune.com/
Deltarune is the sequel of Undertale, the indie hit of 2015. If you enjoy that game and the first chapter, it's time for some more!!!!

It's also available on Steam and Itch. Itch went down for a minute due to Deltarune, so it seems GOG has been SPAREd a similar fate by getting the game later.
