"[Gravity Hook HD] provides much of what I loved about Canabalt, only in a vertical climb instead of a side scrolling run... it really is a much better experience with your finger."
- Touch Arcade
"Gravity Hook became a high score-focused game that I could whip out and play any time, making it a title that'll be a mainstay on my Apple devices for a long time to come."
"...the presentation here is simple yet exquisite. With hand drawn backgrounds and lovingly-detailed nodes, the art direction manages to be a perfect fit. Baranowsky’s soundtracks are among the best in video games today..."
"...not only easier on the eyes, but easier to play as well."
"You can feel the evolution of Semi Secret's reflex-intensive design ideas in [Gravity Hook HD]."
"Like the [Canabalt], Gravity Hook HD is punishingly difficult and encourages a just-one-more-game mentality."
- MTV Multiplayer
"I can't say it's as fun or as simple as Canabalt, but it is colorful and addictive for sure."
