This has the potential to be a very moving game (I'm Irish).
It needs a bit of work though - I didn't seem to be able to plant any oats.
I grew barley and spuds, but once I used up all my seed, I couldn't grow anymore barley.
The harvest seemed to go direct to the rent - there seemed to be no way to replenish them.
A shop was mentioned but I couldn't figure out how to visit it.
I died unexpectedly before the end of the first season even though I appeared to have eaten enough.
If you work on the above items you could have a game that highlights the tragedy of the famine in a very powerful way - you're nearly there!!!
A very thought-provoking jam effort.
