Could be but is not all it's cracked up to be
This game relies on a lot of little cheap tricks, like super timed jumps, little nudged movements, and sometimes the space-time based powers really make no sense in how they're applied. I'd say 50% of the puzzles are cheap 25% are clever and the rest are just no-brainer so-so types. I guess in that sense it's a blessing the game is so short, although that itself is another issue with the game if you pay full price since there is 0 replay value once you've solved it. The plot imo tries hard to be artsy-fartsy for the sake of it and doesn't really lend to a solid game-ending conclusion but it's so inconsequential that it's easy to ignore that as part of the game.
Having said all that I think it's still worth the purchase if you can pick it up on the cheap mainly because the presentation is so fantastic. I'd say $5 for it is fair but anything more and you're cheating yourself.
