nice game.
difficult start, if unlucky.
after surviving the start, tho, it becomes a matter of spending all your money.
i guess the start is fine. maybe add more negative squares that take a while to become positive, so a player cant simply buy all and win.
buying everything in the shop should bankrupt the farm.
at some point at year 11 the tax lowered back to only 90. not sure if that is intended.
good luck.
