To The Core

A puzzle platformer with a portal gun and shooter elements that tells the story of a failed journey to the center of the earth.

Embark on a journey to the center of the earth and don't forget the portal gun. Watch out for huge jellyfish and remember: "Corporate ethics prohibits wearing the Black Mesa insignia".

Walhthrough:
The last room with arrows:
TIP:
Look at the arrow at the back of the room and at the arrow at the bottom. They are very closely related. And the third arrow from the top indicates the drop height.
FULL Walhthrough:
After the checkpoint, we jump down and put the portal on the back on a large surface, then we fly to the mushroom, where it is already on the ice and two more mushrooms, and we get back on the ice and from this ice we fall down to the portal where the arrow is, and turning back we put the second portal under the second arrow and at high speed we fly over the whole room.
