This is a SUPER longshot but I have a crazy idea and it's totally okay if I'm wrong. I have a very casual community with mostly console players like myself. I'm noticing a lot of negative feedback on how much they don't like the new codes on the map that they need to interact with to pull sprites. Some even saying they just run past them on purpose now because they are not good at putting in the code or are just scared of getting shot in the open while doing the puzzle. Also console players and some PC players who have high settings are having a hard time seeing through the tall grass or water when entering some of the codes.
First idea that would require very little changes: Remove one character from the sequence for each rarity. making it a little bit easier for casual players to get the code faster.
Second idea that requires a lot of changes and rework: Bring Sprite Chests back and remove the codes. Change Cheat Master variants to do something else. ( maybe 25% chance of pulling 2 sprites from Sprite Chests only )
