Thank you so much to everyone who commented with suggestions! Some really surprising ones in there too that I'm very much looking forwards to playing soon. So far thanks to this post I've grabbed Heat Signature as well as Shady Part of Me and I'm replaying Dysmantle. I've also wishlisted Creeper World 3: Arc Eternal and will nab that the minute it goes on sale.
Edit: Ooh and I'm also looking forward to the release of Outworld Station on Tuesday. That looks like a really interesting top down, space station factory automation game :)
