Well, the addition of the office was supposed to fix that i.e. moved all the location buttons to one place, so that the bottom bar can be less overwhelming. The only thing I can think of to improve it is hiding more buttons by making players scroll down, but then I risk them just missing them.
No clue how the sealing chamber can be made so less information is displayed. Which akabur game should I check out?
By the way, I thought that photo was cool, but I get what you mean.
The photo was a classic way to imply "confusion by data overload".
The problem is not to have less info, but making it visual, "gamy". FUN. The clarity you have now is very good, but its an excel spreadsheet. You need to make the spreadsheet fun. The seals could have different shapes/ colors; the office and locations could be a "real" place in the world via map, and every location has an actual building icon that you can memorize by shape and placement in the world map. Akabur games are simpler(in a broad sense they are just an excel spreadsheet game/ vn) and are structured like that. About akabur, I won't get into that because fans can kill (I personally like princess trainer and four elements, because I like the characters). There is an H game general on vg you can ask for more info.
To conclude, I'm a function over beauty guy myself, but we need to accept that games mostly sells for art/presentation. Ihmo if you work on the art side of your project in a few months you could open a patreon and chill.
