I was able to teleport the containers using the portals which I accidentally did, causing the level to be incompletable until restarting, with the grappling gun, it was a good feature however with no air strafing in the game, it made it hard to grapple to most places and I found myself just using the rewind feature to my advantage and gaining velocity from going backwards and forwards over and over.
Good game with some cool features and cool shaders along with well made assets, however, a lot of bugs were there and also made the level incompletable at some point
