I've noticed the tech points issue as well!! Good, it isn't just me being a loser and not knowing how to play lol

Low always, I'm still on low on plant tycoon and fish tycoon too. I never have gotten all the fish on the tycoon.

Low for now. I just bought the game a few days ago, so I'm starting out with the easiest level. After I've worked with the game a bit I'll try the more difficult levels. This is the approach I'm taking with Plant Tycoon and Fish Tycoon, too.
