So many hours spent playing FTL. I was against getting Netflix subscription (we already had 3 streaming apps) until one day I noticed Into the Breach is available on mobile if you have a Netflix subscription. Can't believe I'm subscribing to a streaming service to play an indie game (wife turns out enjoy Netflix though).
I thoroughly enjoyed FTL and Into the Breach.
Another I thoroughly enjoyed was Jupiter Hell, which seems to be a fast paced game, but is actually a very thought provoking, turn based game.
