This is one of my favourite flash games, I've played it through a few times, and it pains me to see so many people complaining about a great game for no reason.
Guys, this came out before Company of Myself, you can see it for yourself in FreeAsANerd's Author Comments: "It's a moody little puzzle game about a hermit that expands on the mechanic seen in games like Cursor*10 and Chronotron." Scarybug didn't steal the basic idea for the mechanic, at least not from Company of Myself, but more importantly: both games are well made and entertaining. Games do not have to be totally unique to be terrific games.
As for the Simpsons thing: Scarybug didn't even write the description, there is no mention of the Simpons reference in the game itself. But again, the important part is that the game plays well and is fun!
This is a great game, with lots of challenging and entertaining levels, and I'll probably play it a few more times at some point.
