I could've had a better time, but I missed the lever at the start and didn't notice the Shroom early enough.

P.S.: At first, I didn't notice the Shroom, but then I heard the Spider noises so I turned around and I decided to go and jump into the hole (because I thought the Spider might be there) and then I noticed the Shroom on the ground. That's why it may look weird ≽^•⩊•^≼
