Hi, I wanted first of all to thank you for this game! Very nice and relaxing, reclaiming the wasteland with an atmospheric music background is truly a zen experience.
Secondly, I wanted to report a small bug in the 0.40 version, where undoing an action causes a reload of the map (this is probably WAI, though a bit annoying), after which "DEBUG TEXT" is visible in the top right corner.
I tried grabbing a screenshot for posterity but it came up blank. It should be easy to reproduce anyway.
