I've looked all over and I can't find the key to the Hyena gate in the Van'ki prison. Does anyone know where it is?
I had this same issue, it's a face palm moment when you find it.
Check the shack on the way into the prison, and you'll find the "evidence room key" in a tiny chest on the table.
Because it doesn't say "Hyena Key" I was confused when I could suddenly open the evidence locker.
I imagine the design intent was for the player to find it on the way in, and for the "Evidence Locker" label to be a bigger clue than the "Hyena Key" inscription.
For Paccsu -> I also discovered a glitch where I could walk right through the gate without the key! As long as I was not centered on it to read the inscription, I could pass right through the tiles on either side which are half wall / half gate.
Note: this was after defeating the clan matriarch of Van'ki Prison in v0.19 and saving, then updating to v0.22 and continuing.
I have found a few other interesting missing collision boxes, but nothing game breaking so far.
Also for Paccsu and team -> entertaining, light hearted RPG romp. Good character design, excellent combat and economic balance, solid level design, and art which fits the story and mechanics well. I think you're well on your way to an excellent product when finished. Good luck!
