There are a couple of issues here, unfortunately. There are only 3 recipes to craft, 2 of them use 1 bottle and 1 bottle of eyes. 2 of them use the wing. The other items, rat, feather and broken glider are used once. This means the player will consistently run out of bottles, bottles of eyes and wings before the other 3 materials. Even with perfect luck, you can only craft 12 items per day, which is not enough to clear the 14 day quota. Assuming normal gameplay, the days are way too long. You just have to wait to restock items at the end of the day. But because you might need some of today’s leftover items for the next day, the strategy becomes putting all leftover materials on the floor at the end of the day. Not that it matters really since, as I said before, it is mathematically impossible to get 3k within 14 days.
I encountered a bug, where I place 2 sets of all the required items for a recipe on the floor, then press space to activate the circle on top of it. This for some reason only consumed 1 set of the materials and gave me 3 of the resulting item. This in itself could potentially be a fun little mechanic to build your game around. But it seems to be unintentional here.
