That is bad. I described it on the itch.io page, but in short, you throw stones with the left mouse button, enemies and the giant can hear it, around the enemy and giant, there is a hearing area, which is a semi-transparent grayed area. Enemies have a vision cone; if you or a giant happens to enter it, the enemy will attack you. You need to open all the gates and escape. Only the giant can open the gates by moving close to them.
I hope that is clear, and thank you for playing it!
