Very neat. I like how many different strategies are possible with all the items, but I feel there's not enough incentive to use the more complex ones. My first run I just used regular weapons and stacked a ton of bonuses on my Brutal Spear, and won on my first try. I've since tried archery and magic builds, but I always end up dying to one of the early bosses. (Incidentally, the badger boss' rising power is really brutal for a first boss. If you can't wipe him out fast, you're doomed.)
I think the main issue with archery is that it requires you to get a lot of the exact right items in a short timespan; arrows and bows are useless without each other, and arrows are rarely superior to melee weapons unless you have multiple. It takes a really long time before an archery build becomes viable, during which you have to carry a ton of dead weight. The archery kit event helps, but of course that's random. Maybe there could be some weighting to random drops to increase the chance of getting arrows if you already have a bow and vice versa?
I feel the game also has the same issue as a lot of RPGs, which is that battles are won before they begin -- strategy matters far more than tactics. Because enemy attack patterns are so simple, you can almost always win by doing the same thing each turn. I think that more mid-battle backpack manipulation would help with this; the curse enemies are a good start, but maybe they could reorganize our items as well? I also feel like reorganizing shouldn't take an entire turn of combat, as it's basically never worth three weapon attacks.
