Thank you so so much for playing the game, your kind words AND the feedback! We are aware of these issues and unfortunately we had little time to clean the game up and do bug fixing etc. before the deadline. However, we are working on a more polished version of the game which we will be releasing after the voting on the game jam ends to resolve many of these issues that you mentioned! Therefore, feedback like this is worth gold!
Also, we are so happy that you appreciated our own "new" mechanics and takes on the original games. Since this is a top down 2D game, we lost a lot of the potential for puzzles that the original Portal and Portal 2 had, being in a 3D environment. Therefore we wanted to create some NEW ways of making puzzles, and by extension not making a complete copy paste of the originals and giving our own spin on it!
