I"ve had this for free for quite some time

This looks quite interesting. Hmm, I haven't bought any games in a while. . . Must resist temptation to add to backlog

Not really into tower defense, so I'll probably skip. Nice music though.

From the trailer why it felt like a mix between rimworld and factorio? It's not a bad thing tho I put it in my wishlisht.

Sorry GOG, I already bought this on Steam ages ago. If you actually let us know it was coming here, I would have waited.

Can you resize the UI and the fonts in the game ?

Yes as you can see in the attach

There is an interface scale option ranging from Auto, then 1.0 up to 4.0 scale. I found no separate font settings.
I attached a picture of the available settings. Interface also scales text. Two example pictures attached, one for default scale, one with 2x scale. (Resized to 70% of 1080p as the resulting files stepped over GOG's 500KB file limit.)

EDIT: Nevermind the edit, mistook another reply to have me ninja'd. Swoosh.

Yes with the INTERFACE SCALE option but it's a sort of zoom (see attach)
edit : ninja'd too ;)

Thanks .

A bit late, but very good pick. Bought. Glad I didn't bought RtR on itch before.

I hope that GOG could also bring us KeeperRL at some point.

I'm enjoying this but I'm starting to get frustrated. Citizen AI is very suicidal, pathing along the edge of enemy territory and dying. (And replacement citizens aren't the easiest to come by.)

Can't say I've had that problem...I've lost a few to fire elemental attacks, but that's about it. Make sure there's a buffer between your territory and the enemy; large fire pits are good for that.
