This was a nice game! I like the story, and going further and further back in time. I was initially very rushed, and wished the cutscenes would pause the timer (or that manual pausing was implemented), but very quickly I got to the ~1000x slower speed limit, and it became a non-issue.
It was a bit slow at times, and nothing I could do sped anything up. It said buying the auto-buyers would potentially speed them up, but I literally would buy 100 with no perceptible difference. Made it really annoying in the last 2 sections, just needing to wait because I need so many items, and they are generated at a set speed.
