Hey, have had your game wishlisted for a while, and as a programmer/Factorio player/"guy who grew up with a pappy that had an awesome model train setup and took me all over to model train meccas", I just want you to know that I think you're filling a niche and expanding the genre in a very meaningful way!
Honestly, I want to say it was your twitter ads that caught me? I'm pretty entrenched in the indie scene on twitter, so it was either an ad or just a post that got in front of me.
That makes sense. I've been running a bunch of ads, and honestly I think they are a powerful technique for indies. We don't need to convince press, journalist, or a publisher. We can let our game speak for itself directly in front of players.
It helps that game ads are a lot nicer to look at, so our cost per click is lower than the typical business or crypto centric ad on twitter.
Chin up, and good luck with launch!
