I really like the robot (I get the ref hehehehehe).
Otherwise, the game could be awesome with some explanation. Also, maybe speed up the rotation for the last level could really improve the experience. 👍
The idea of moving around just by positioning the portals is pretty good, especially since the feeling (the movement) is pleasant (I was a little worried it would make me dizzy, but not at all).
I really enjoyed the game. An undo button would be amazing, and preventing the music from resetting with the level would be appreciated. It would also be amazing to have a scoring system based on the number of blocks used per level.
Really love the design and the atmosphere. A bit sad that we can't hear much longer the musics in the past (maybe a bit of animation to give a reason to stay and listen this gorgeous music)
Thanks for your feedback! Yeap, I'm a little disappointed that the physics are like this. However, if you enjoyed the atmosphere and the final look of the game, then I'm very happy !
