Thank you for playing, and I'm happy that you enjoyed the design!!
The perception stat is indeed a bit of an odd one out, so fair criticism! I initially intended for it to be used as a shortcut for a couple more "puzzle" events, buuuut the ideas didn't quite fit into the development timeline / game vibe overall haha. It ended up just settling as a utility stat for item drops/damage boost. Valid comment on the crit indicator as well!
Congrats on 100% the game, and it's nice to hear that it still held your attention through it all :D
