I didn't find the font too difficult to read but the "vision sensor glitch" definitely took a bit to get my head around. Interesting concept though so I'll continue to mess around with it more and see if I can get further!
Almost every my play tester (friends) struggled with font so I found it necessary to mention it :)
"Vision glitch" effect also was one of the biggest struggles for play testers, but it's the main game mechanic which I wanted to implement and add difficulty to the game.
