Hey, thanks for your feedback!
- The "dumping all your money into a single 10x building" strategy works at first and you'll be able to research a lot of new things (including a way to auto-conquer galaxies), but it plateaus and you'll have to find other strategies to keep making numbers go up (megastructures, terraforming etc.). I do agree that you don't need many planets at all to reach very high numbers, I would like to change that! Though looking for and conquering specific planets with very strong auroras or deep caves may be interesting to boost progression.
- The reason the collect all button is there is for performance, if a player builds thousands of buildings and the game checks for each building (with possibly varying levels, bonuses, etc.) several times per second, I don't think it will perform very well. What replacement do you have in mind that performs well?
- I believe adding the plateauing mechanic on upgrade/technology just makes numbers go up slower and everything would take more time, or maybe I'm not completely understanding.
- You can mass-overclock (only on one planet) by shift clicking an overclock in your inventory, then pressing shift again to select every building of the same time, then clicking.
- For the materials, they'll once again become useful (and then useless) once you unlock megastructures and terraforming.
