Loving the game so far, I've never played anything like this game before, and it's been a total blast learning this game! Here is my 2 cents as far as UI stuff goes
The biggest weakness in the UI is imo the event popup area. Right now, all of the text is quite small and white, you cannot simply glance at it and know whats going on. What I'd like to see are some visual queues for the different events, and have them be basically the same size as the resource icons on the left. So when something happens, I can glance at the notification and click it to take me to the event, but it wouldnt require me squinting at my screen trying to read bland white text.
One other feature that would be nice, but is nowhere near as important as my previous suggestion, would be to have the initial resource bar that shows at the top while scanning be a permanent feature of the UI, or at least expandable when needed. Would be nice to see the resource totals after you drop your colony while the map is still being explored.
Thanks again for this gem of a game, good luck in future development
