Nearly fifteen hours in, it's quite charming tough flawed. The combat system has potential, too bad that you're mostly facing legion of trash mob. There is some kind of color system giving you a rough estimation of the opposition power level, but I don't find it reliable, I normally don't have difficulty winning against yellow, but did got my ass kicked by mob appearing in green and even white (probably because I did not have full party).
Lot of dicking around to do, but it's probably too much at some point. What's the point of having TEN different tier of equipment AND a rarity system on top of that ? It just create needless clutter, and certainly does not help making the crafting system feels worthwhile. Crafting equipment are very good on paper, but you probably won't get the blueprint before starting looting the next tier of item. You need to be on the prowl to look after people strong enough to carry a good blueprint, but weak enough to won against them in a spar.
Speaking of powerlevel, MC is nerfed compared to the rest of the cast, and I'm not sure why, everyone got highest base stat for a given powerlevel. Meteoric ascension is one staple of the genre, but it steel feel weird to rise from apprentice to master in a couple of day.
Don't forget to save before entering any city of new map, because you might trigger event that you won't be able to beat.
