The wizard talking all the time is quite annoying and it slows the gameplay down a lot.
I had some problems playing on windows: the game is windowed and can't be enlarged, but it looks like the aiming was considering the position of the mouse relative to the whole screen, not the window, so it felt very awkward.
I also found it unclear how to actually throw the ball towards the beers, because sometimes it looked like it was going backwards.
The idea and presentation are very nice, the problems are just with these technicalities
