I absolutely loved Thousand Empty Light, and the way it was executed (especially all the little secrets, codebreaking etc - I think I've figured out/discovered all of them). I was playing from a printout of a PDF version I got from DTRPG but I ordered a physical copy too just so I can have a proper version :). Thanks for making this, Alfred! :)
I'm going to leave my long playthrough write-up/journal here for posterity too (I try not to spoil too much of the secrets!):
