Really glad you enjoyed the game!
While I have played (and loved) Outer Wilds, the similar timing is very much a coincidence. In fact, when Santorini was first added, I believe it was closer to 25 minutes, but it got brought forward for balance reasons.
The contrast of the red test was brought up before, and I did adjust it. Though it has just occurred to me that there are at least two bits of text which can be coloured red, and only one of them may have been adjusted. So I'll check on the other one.
If you follow the game on Itch, I always post an announcement with major content patches, so you should get notified of those.
