Parallax

"Love first person puzzles like this."

"As others have already stated it's broken"

"It's a cool game, but every time I exit and come back, all my progress is gone. I don't like having to always restart. Please fix."

"Lack of a storyline and infinitely recycled touchy jumping mechanics hurt an innovative take on the frequently visited n-dimensional puzzler. Has portals but little else in common with Portal so prepare to be disappointed if you're looking for something like Portal. Are we owed a story in 2016 for $10 on the Android Market? Yes, we are."

"Looks interesting but doesn't support the Xbox 360 controller well enough to be played and doesnt specify as much in the description. Refunding"

"Critical functions are not working on USB otg gamepad. Left-right looking for example."

"Only played first few levels but very cool so far! Also has excellent gamepad support."

"Great game so far and the devs are very responsive. Contacted them about the look inversion and requested d-pad support be added in the menu and both were fixed later that evening. Great job!"

"Nice game. Similar to Portal, but look inversion needs to be fixed."

"This game is so good. Very clever level design and use of puzzles to make use of the alternate universe (if you will) to solve each level. Starts out easy enough but ramps up pretty quickly once you hit the second chapter. Excellent job!"
