Press E.
I just noticed that there is a bug that no one told me about until this point... Wow. When you get there, if you don't do anything for a longer time, the letter "E" should appear in the air. Instead, "Q" does, haha.
Good thing I also wrote the controls in the description.
Thank you, and please feel free to take inspiration as much as you want from this game, I'm happy it inspires people.
