Yeah this game is fundamentally broken, even the itchio version is bugging out for me. The main thing is that the arrow just doesn't load most of the time so I have no idea where the minigame is supposed to be
The arrow only appears if you press the action button when close to an item, you must press it again to see if you're closer or father. If no arrow shows up, there isn't an item around so try moving and pressing action again!
