There's a solution that works (perhaps) 100% of the time, if I may - 1. Keep building house + lab, patch the rifts when they appear. Keep doing it to accumulate SU 2. The turn when you start with 40 SU, build two factories and a temporal field generator beside them 3. Build two labs in the range of the field. Patch rifts if they appear 4. After accumulating enough SU and RU, build temporal labs and have them covered by more temporal field generators 5. Build the rift generator within range of a field. Now just wait and patch rifts that appear afterwards.
In fact the first step takes an enormous amount of time and the following steps are very quick. Basically the game is won after the set-up is done. Not sure how often the rifts appear. The rate at which they appear decides how long the first step takes.
The tips in the first couple of days are pretty useful as they provide context for the functionalities of special buildings. The game delivers a grim mood which is fitting for the theme. Good job :)
