you are the horde" was the opening idea from day one, that kind of clarity usually means the whole game design flows from a strong core, good sign.
Sounds like you've already got a solid promotion mix going too, devlogs, creator keys, Reddit, and clips focused on the breakthrough/warlord moments, that's smart since those are naturally the most shareable parts. If it ever gets to be a lot to juggle alongside dev work though, that's actually what I do, short form video editing and social support for indie devs, so happy to help take some of that content load off if it'd be useful down the line. I'll definitely give the game a go either way and see where I land on the leaderboard, consider that a challenge accepted!
