Some more great games that used to cost money but are now free to play. All three games are highly rated and look pretty good. OESE reminds me quite a bit of FTL.
In fact, Grass Cutter still costs money on both PS4 and XB1 so count yourself lucky to be playing on PC. ;-)

Nice to see more games in my price range
