Really fun to swing, though more air movement would've been nice, found myself swinging in the wrong direction a lot. I feel the portal mechanic is also a little out of place and the game should've focused on the swinging on its own, rather than portals. The reverse time mechanic is also really overpowered, as I found myself spamming it to make sure I land my jumps. Maybe add a timer to the levels to challenge the player to finish it as fast as they can, to deter this?
