Also you are missing the Klense trading card found in Water World, the monolith trading card found in Pool, the old bright moon trading card found in bright moon, the pointer trading card found in the Kindness Sector, the stupid bird trading card found in Bird Cage, the Stupid Cat trading card found in Hallway, the Tiny Igni trading card found in Igni Chunk (igni chunk is linked to from somewhere in Lantern Lake), the Brigni Ball trading card found in The Outskirts, the Ispura trading card found in Limbo, and the Igni Car trading card found in Parking Garage. I think thats all of the ones your missing let me know if I missed any.
I resign myself to defeat; 280 links later & I have 17/18 cards (I'd like to compliment you on the different pause music by the way! Found that out through looking for the cards), I can't for the life of me remember how to get to the Bird Cage to get the Stupid Bird card. I remember getting there so easily the last time I played :( Also while trying to scrounge up the Brigni Ball (good sentence), I found that I needed the Outskirts Keycard that I can't seem to track down, any pointers? Foldy Oldy is now my new favourite character btw they are such a sweetheart I love them to bits with every fibre of my being. Also, did you have a discord server or anything like that? I'd love to join if you did!
Bird Cage is a bit weird to get to, you have to die to Igni who is in Brick Plains but I think his spawn is around a 50 50 chance or so? The Outskirts key card is located deep in War Museum but it's not really needed for anything just a bit of lore on a CRT. I sadly do not have a Discord for the game and probably won't make one unless the game randomly gets really popular. (If you want sneak peaks though I do rarely post some here.) Again thank you so so much for playing!
