I know this is an oldish game, but I was browsing incremental games and I ran across it. I agree with the other commenters this is not an incremental game it is just the beginning of one. That is fine, but you have a ways to go.
First, things are horribly unbalanced. Meat sells for 2 euros, corn sells for somewhere around 0.3 per. Shepards pie sells for 4 euros and costs 10 meat, 4 corn, and 1 potato (which has no value). Therefore to break even with the pie each should be worth at least 21.2 (the cost of the ingredients), but that would still not make it worth the effort.
Same thing with farmers, farmers double the crop production, but corn has little value and potatoes have less so you may double the crop output but then you more than double the cost of the farmer each time making them more or less useless.
Unless this is a commentary that the irish suck at economics you should rethink the model so that the player can always do more with what they get.
