All his games have weird little bits of information. This is what I have so far. (yes I played all of them)
MO - 9+HN - 467767NY - idkDPTG- Look inside. 467767TB - idk6B - LHFDMY, HDYLFM
the 9+ are the number of +s that you get until the weird jump scare thing happens.
is this the order that the games came out.
