I found this game quite fun. It compensates gameplay with a really compelling and funny story and great atmosphere. The ending was (maybe unintentionally) really funny, where the game simply closes to desktop without any win screens or anything.
That's not to say there wasn't any gameplay. I liked the way the game switches it up, with different drinks pouring out differently, even though most of the time it never posed too much of a challenge. One thing I noticed is that some drinks (like the cola) blended in with the brown background. Also as a non-drinker, it wasn't always immediately apparent which drink was which.
Overall, this was a very fun game, to quote my partner, "I could hear you wheezing all the way from the bathroom."
