The controls were quite tricky for me, as a left handed person I am not good with wasd, I prefer the arrow keys.
Also the watering can was a bit tricky to distinct from the player, as it has a similar color, together with the position of the carrying item.
Otherwise I got stuck, after upgrading to the second table to place items on, it looked like I was standing right between 2 of these, above where the watering can originally can be found
