I too found the letters unreadable, both because they were tiny in the webGL view, then when I went fullscreen that font... yuck. I dont think farm grandma wrote in that font ;)
I did manage to clean the stall unlike many people but the FoV was really unpleasant so I didnt do any farming.
I did steal grandads crops through the glass because im a farming ghost though :D
What I did play was pretty solid though, good use of synty (or synty-like) low poly assets, you included some environmental storytelling which I love.
You did fall into the 'seasons' theme being 'ill make a farming simulator about making money' trope. Coulda made granny and grandad old hippies doing subsistence farming (i dunno maybe in the letters they were :D )
Overall though solid work for 5 days.
