I have succeeded in banishing Cthulhu. I also had previously recovered my memory, this bad ending for not performing the ritual in the right place was super cool.
The game looks pretty good and atmospheric. Movement is kind of smooth and then kind of pleasant but it's too slow for my taste anyway, I think keeping walking ahead when keeping the button pressed would have helped in this one as it uses slow movement (with instant movement it does not matter). One thing I really like is that the difficulty feels appropriate, the game is not hard but it's not completely trivial either and there's actually little chance you'll win on your very first run, and then the game is fun to play.
This was a cool entry, thanks for sharing.
