grabbed the battle chasers, thanks!
as for Graveyard Keeper, I got it a while ago and for someone who really doesn't like lifesim games (Stardew Valley almost bored me to death), I had a decent amount of fun - it's much more streamlined than SD, at least at the beginning, always giving you some goals achievable in a reasonable amount of time. Writing is also pretty good.
btw really curious as to what the last 2 epic freebies will be, I'm hoping for a decent indie metroidvania, though at this point I feel like I might have played them all
