This game is truly a tragedy, it has such a beautiful environment and a very well made, very well animated, very well designed adorable character, it has a very simple and intuitive gameplay loop, with diverse nicely styled customers, it even has some cosy music and very well placed sound effects.. but then sadly it is held back by what seems to be a ton of bugs that make it virtually unplayable.
I'm not sure what recipes are currently supposed to be in the game, but only able to actually combine bags, everything else would just result in either the base item or a different item ending up in my item slot, with the held item being invisible and cannot be dropped. For some reason 3 blue potions turn into a green potion, sometimes occasionally I was able to just pick up a green potion at the blue potion table, and I couldn't find a red potion at all.
The biggest culprit among these is the invisibility bug, where it seems that everything other than the Bag is invisible until picked up. This combined with the incredibly tiny interaction range means that even after sorta figuring out where the potions, bags, pouches, etc are, it is still very frustrating just to pick up any of the items.
This would be manageable, but the problem gets even worse where often, the items will be invisible when transmuted and automatically picked up by the character, it appears that these don't register as actual items as they cannot be dropped or handed off to any of the customers.
I can relate because most of the last day of the jam I spent bug fixing, a lot of the code for my project was so messy it should be illegal. If I had handed it in before that final day, it would be in pretty much the same state where a lot of the interactions didn't work either at all or as intended.
In the end the only proper way to play the game was to combine bags, and take those and the potions to the front and drop them off for customers to pick them up later. The design of the game is great, it's very fun rushing around picking up, dropping off, and combining items, it's just a shame that the issues explained above got in the way of that fun. I would really love to see this game in a working state, and am also looking forwards to more of your great environments and characters in the future!
