I noticed your road map is a bit vague and hard to find (in the media portion on your website). For early access games I’ve found that a good road map has been essential to keeping my interest throughout the process.
I’m sure there are many good ones out there, but eremite games really nailed it on Against the Storm. The road maps kept players confident they were consistently updating the game while providing timelines on near-future updates so players could jump-back-in when something they find interesting pops up (playing too much in early access can lead to fatigue/boredom even if the final product is great).
