Hi! Thanks for trying the game .You can enter the portal by just clicking key E. And if you push the box near the portal before you enter the portal, You will see the box changed.
Thanks for your comment. At first, I tried add portal gun but it broke the game. So I Had to delete the system but I didn't delete teleport system because I didn't have time. Unfortunately ,It caused that bugs in game. In the future, I hope I would become more good at game making. Thanks for your opinions.
