gave the demo a try, really interesting, but there's a couple of things that kinda irked me

1, some form of timer, for watch or external, would be a big help. i'd imagine that in the later stages of the game, you'd normally have several brews going, so having to manage several separate times would be a hassle. maybe even have it so that if you have a bunch of timers, and one go off while speeding up time, the watch immediately snaps to x1 time

2, option to "dump" while pouring. a good amount of ingredients you can get in exact measurements, so needing to slowly pour in a 50kg packet of something would be kind of boring.

3, proper options for hud and brightness. at times it's a bit hard to actually see what the text on some parts of the hud are saying, so the ability to control that would be a BIG help

and that's about it. i've got a couple more suggestions, but i think they might be already covered from a cusory glance
