What are the differences between the trial and registered versions of Village Sim?

In Trial version you can only jhave 7 people and cant buy anything

You can actually purchase level 2 of harvesting in trial mode, so that your villagers can learn to farm.

really????

yes indeed-ie!!

Yes. It was thought to be too restrictive without farming, because all of your villagers would die after the berry bush ran out of berries, so that's the one tech purchase available in trial mode.

With level 2 harvesting being available you can keep your population running forever (in theory) and keep gaining tech point indefinitely (in theory) so if you want to save up some cash or wait to the end of the month to buy the registered version you can without penalty!
