All the crystals that appear "available" to unlock are in fact possible to get by playing normally, I did like 3 or 4 different runs to get them all the first time I played it and funny enough I got the same idea to just duplicate one picture and renaming it to unbug the game, but this means you don't really get to see that specific scene which, in the case of actual new scenes I found in the cheat menu (like the 6th crystal for the hypno guy), was really disappointing
.. the file is even named " ci-en.png" so they're just place holders for now... UNTIL WE GET THE FINAL VERSION BEFORE DECEMBER ENDS FOR WHICH I'M REALLY EXCITED ABOUT!!!!!!!!! LET'S FUCKING GOOOOO NAU NAU KINGDOM!!!!!!!1
