Incredibly unique mechanic that makes exploration and puzzles fun. I respect this as much as Portal in the sense of it having a really a mind blowing feature and thought out level design but I can't help but feel like there could've been more to the game beyond the roughly 3-5 hour adventure based on this one mechanic. Perhaps a more interesting story, additional platforming capabilities, or anything really? I hope it one day gets a sequel that expands upon the excellent foundation this game provides.
