I really enjoyed playing this game, my main problem playing through it was the fact that you need to feed inedible foods to Grandpa to proceed with the good ending. My first playthrough I had trouble finding the necessary items until I literally only figured out the mechanic at the last week.
The game is designed in a way that it is feasible to get everything done on the last week, ie in one playthrough, but also getting the good ending is contingent on doing a lot of exploration + reading documents + talking to Grandpa. i sort of did want people to get the bad ending before the good ending just because it might make them explore more and seek out some answers to what is going on. however this is the first game I have made that could possibly be called non-linear, so it was definitely a learning in experience in regard to this type of game design. I am happy you ultimately enjoyed the game tho!
