If you have enjoyed FTL and are looking for more of the same, check out the multiverse mod package - adds a ton of content including overarcing story elements and unique ship and race unlocks.

One more recommendation I haven’t seen here - Dave the Diver. A cosy blend of underwater exploration, collecting, and selling sushi!

I really loved rocket slime as well. There’s a spiritual successor called connectank on steam that gives me the same vibes, and has fun co-op!
