Also keep forgetting to give kudos to @Mirefox for mentioning Chai - just sorry I didn’t look into it sooner!
Quick review:
Vaguely reminiscent of Potion Explosion - given the need for ingredients and trying to get what you need to “brew” tea - but with a few more choices and mechanics thrown into the kettle for good measure.
Less of a puzzle vibe although there is a little of that too.
Haven’t tried async yet but it is Digidiced so assume it works the same as all their other games.
