What an absolutely fascinating game mechanic! Normally I don't like being thrown into the unknown while I'm trying to map out a Metroidvania, but I'm glad I stuck with this. Wow! This game was really clever! I loved all the QR messages too (providing useful hints and backstory,) but how did you honestly expect us to scan the one in screen -1:C as we're falling?! I ended up taking screen grabs on the QR code screens and then scanning them that way (I was seldom quick enough before I blinked otherwise.) Also, did you know you have two 2:B screens? Maybe the second one was supposed to be the missing 2:C? Well done on a great game, and the music fit perfectly too! Cheers! :)
