There's a lot to say here, first the game fits the theme perfectly well since you're a farmer that (apparently lost their memories) and has to start over their fair without remembering how to take care of each plant. This is such a great concept and in a full game can be explored very well (if you put other NPCs it would be interesting having dialogues about their past and their relationships).
The mechanics are Stardew Valley BUT with the addition that each plant requires way more care, instead of just watering them you have 3 other options (besides the singing one, i couldn't figure out what the other two were, I'm interested in what would be the names of the actions). And there was lots and lots of try and error which may seen more frustrating but it makes so so much more interesting. Even making you think you're doing everything perfectly well and then the game strikes you with something new (like the flower killing the other while you're [gathering?? i forgot the word, picking it, farming it],,, i almost cried😭). So it's like Stardew Valley but you made the farming of it so much more interesting and that's awesome.
I was a little confused about how to gather more library point tho, for some plants it was easy to get a lot but for others i could barely get it, even interacting with them didn't do much compared to others, so my only more negative feedback would be maybe making more clear how to get points and depending maybe making it more easier to get.
This game is my top 1 of games I wish to play for a full version, it has SO MUCH POTENTIAL so please consider continuing on it, I would love playing more of it with it having more things to do in the town, more people to talk to, etc etc.
10000/10, the art and music is beautiful too i forgot to mention!
