Very active and very slow, not a good combination. Weirdly polished visually, which is pretty much entirely responsible for the second star I'm giving it, it's strange how much effort they put into the visuals and sounds, even having recorded voicelines...and yet they couldn't make the upgrades actually feel like they do anything. Hold down a button for 5 seconds 5 times, buy and upgrade, and then you get to...hold it down for maybe, 4.5 seconds per instead? And the upgrade cost outscales your speed you gain from it.

This MIGHT get better with later upgrades, but I didn't play long enough to find out, as it starts slow and just gets slower, it feels like. Also, upgrades don't appear to be sorted in any particular way at all, normally those would be sorted from cheapest to most expensive at base, for player convenience.

It's genuinely strange to me how much effort they seem to have put into this, but it's like they never playtested it to see if it was any fun. As such, 2/5 stars feels fair, with how active it is, having to hold down a button. Oh, and if you think the combo might help, you get a 3x bonus for that ONE drink at base, before the combo resets. So at the start, every 10th drink gives 3x, it's a pretty small and infrequent boost overall, still doesn't keep up with the costs of the upgrades at all, as far as I played, which again, wasn't very far, because it was really tedious.
