The game's main mechanic is "performing actions while time is stopped." While time is stopped, you can throw punches, but instead of the punch occurring immediately, you create a copy of yourself at the position of your attack. These copies will perform the action when time resumes.
To beat the puzzle, you need to:
○ Stop time between both buttons.
○ Throw a punch while standing on top of each button.
○ Resume time (you can do this by pressing Space).
Your "time copies" will activate the buttons and allow you to pass.
Ps: thanks for the comment. Really happy that someone liked the game. 🥹
