If you have one, the game does support controller inputs as well!
Moving the camera around, I mainly put in so you could avoid blind jumps that might put you in the guard's line of sight. However, if it's trivializing things, I might make it where you can only look directly around the player's current position.
Yeah, the timer might be too high, but I had concerns about people losing time trying to figure things out. I did want adequate time for people to mess around and experiment with different ways of completing the levels. Though, you're probably right I made the timer too lenient.
Some areas can be avoided entirely and that's by design. To fit the "Free Choice" theme, I made it where levels (especially the later ones) are open-ended so you can find your own route through it, so some level elements you might not use for one run. Some methods will be harder than others and some even let you cheese the level completely! I wanted it to feel like a "Choose Your Difficulty" option but its baked in the level design rather than something you pick in a menu.
Thank you for playing the game and for your feedback! I'm happy to hear you liked it.
