Hello!
Thanks for your kind words, it really means a lot. We're still working on this actually (even though the first release was 4 years ago!), and have learned a tonne in the process. Scope creep is definitely the enemy here, and we've travelled down more than a few dead-ends chasing cool ideas which never saw the light of day.
We've hit so many walls that we've actually decided to take a step back and build our original game, Liminality, in Unity instead of our custom engine. There's just no end to engine creation, and we want to finally finish a game.
You can read more about Lim if you're curious.

We aren't abandoning Aether Edit though, but we'll be looking to learn from Liminality about what a game needs before we come back to engine stuff.
