Thank you so much for playing!
There are actually a total of 7 tiers, basically for something I want to do in the future :)
I love the compendium idea! The 4th tab in the journal is actuqlly reserved for it but I couldn't get it quite right yet but definitely in the pipeline for the near future :D
I really appreciate the suggestion, it helps a ton :D
I hope you enjoyed the game and stay tune for more :D
