Wow, great people are talking to the devs, I'll be sure to give this one a try when I can.
Just as a peace of idvice however, I've always found it helps when discussing access to games with devs to make an honest list of requirements, that way when one thing is altered and you ask about something else, you don't sound like your dissatisfied.
Depending upon the map, it might not be as hard to label as you thinkk, particularly if rather than specifically a amap with hundreds of different places it's more like a "go to first location, go to second location, return to previous location" type of setup. heck, so long as it's just adding controls and labels, it wouldn't take too long even if there were! hundreds of locations, just a case of copying the code for each label and writing the text.
Generally in games with inaccessible maps, there will always be a point where progress stops due to lack of map access, so the sooner the devs know about this the better.
sorry that I've not tried this one myself and so can't join in on the access requests front, hopefully I'll have a bit more time and brain space for games soon enough, this one sounds really awesome and absolutely up my street so I'll be looking forward to giving it a go.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
