Oh, I'm sorry about that. On the first cup you may have to tap space twice (once to position and again to start), or you can just hold the space button down the whole time
Let me know if it works
Still no luck. Do you have a windows build? When out of focus (tab switching) the first one filled up :/ (I confirm that the glass goes to place and the pouring animation start but there is no filling)
Seems to be an issue on only some devices, could only replicate it in one of three 🙃we'll try to get a windows build
you can check the description on the game page for the link to Win
