For clarity, I'm playing on the public version, which at the moment is 0.6.0
The game starts of pretty enjoyable, with maybe a few hiccups, basically your first travel takes FOREVER, but once the girls start hitting B tier, it turns into such a grind it becomes frustrating very quickly. At that point most skills simply don't give enough exp. Idle games live and die on a sense of constant progression, and while those bursts of progress can become further apart, this is too much. Especially for the skills that have no way to automate, namely navigation, mining, research, and also refining, but that at least tends to give pretty good exp. Navigation and research in particular feel like they need to give either way more exp, or just require less. Right now every skill requires the same amount for any given level, but I don't think that works especially well. Research also feels bad to level. Once you've made three of a given tier of potion, there's really no reason to make more, and they sell for nothing, its very unsatisfying. There's the bones of a good idle game here, it just requires a little too much active management on some aspects and a rather serious balance overhaul
