Question about DemonTower

[T4c0Cat]

This may sound stupid, but I don’t have to complete DemonTower as soon as I get the computer fixed for the sketches achievement right?
I’m stuck on level 4 even after looking at guides and stuff, and I kind of want to come back to it later and complete some other things for the sketches instead.

it is accessible all throught the game until you go after the second ghost clue with Gregg, Bea or Angus. After that you won't be able to play it anymore unless you start a new game.

You do need to complete Demontower at least once to get a sketch for it. It's available throughout the game and it will save your level progress if you quit out, so no need to complete it in one sitting. There's also another achievement tied to it involving the duck character and the hints he gives you.

I recommend using a controller for it since keyboard is too stiff for the higher levels. RNG is also a major factor in how easy it will be to complete. My recommendations as a guy who was stuck on it for a day or two: controller, cheese it anytime you can (the game is a side thing so getting stunlocked is possible and hit detection is bad), and don't get discouraged if you die. You'll just have to get good and hit that zen state as you go on.
