The fishing minigame is nearly impossible on keyboard. On a d-pad, probably doable with placing your thumb inthe center and rocking in a circle, though I didn't try. The game looks amazing, though, which made the fact the most basic fish was barely catchable for me all the more painful.
My knuckles are cracking when I straighten my fingers right after playing this.
Somehow it's harder than Stardew Valley's fishing system /lh
