Nice. I like the walking animation and the background music.
At first I didn't realize the number keys were working because the tool didn't highlight unless I clicked on it with the mouse.
Probably could have used some better instructions in-game. Or perhaps farming mechanics are pretty standard and well-known by now, so most players won't have any problems.
The ambience was so chill, I didn't expect the unceremonious "You suffocated" ending.
Aside from the lack of tutorial or instructions, it's a pretty solid game!
Edit / Update: I see now that the instructions are on the itch.io game page. That's helpful. Thanks
