Congrats for making the game! I can see there is a lot of effort in this, can't even imagine the maths and how you prototyped the numbers and calculations.
The good: The gameplay itself is pretty solid, no bugs, the UI is strange but is organized and everything is readable and cleanly spaced, the progression definitely has room to expand.
The bad: My main problem was understanding everything. There are lots of descriptions that feel too superficial to give any insight into what they mean, a tutorial, starting explanation or some “on_hover” tips could help a lot. Also limiting some information at the beginning of the game might reduce the overwhelming feeling of it all. The second thing I disliked was the lack of consequence, danger, or any type of setback, without it the game feels dull.
The strange: The UI was definitely a choice. At first it seemed really strange for such a vertical layout for “no reason” (I'm sure you had a reason), but after a little while I got used to it. I think it's just because everyone is more used to “normal” screen sizes from other games. The timeskip is too overpowered and at the same time too necessary.
