I tried playing it blind first, but quickly realised it wouldn’t make much sense between the FPS controls and lack of available informations.
Replaying it seeing the screen made more sense but was still a bit confusing. I think you may have misunderstood the theme as “the character is blind” instead of “the game should be playable by a blind human player”
Still, there were some nice ideas such as the scan which could be used to change the game back into the theme.
