A highly original game that plays with perception, usually by converting a 2D photograph into a 3D space you can walk into. This game mechanic opens all sorts of Portal/Superliminal style gameplay - the core setup is basically the same, with a various "areas" you have to traverse using photographs in order to activate a teleporter to go to the next area. Extremely clever mechanics/game design and 'good enough' graphics, although many of the puzzles seemed somewhat generic (however if the devs had tried anything too clever it would almost certainly frustrate rather than engage, so I can see why they did what they did). If the game feels like you are struggling it will offer an optional hint to help you out. I used it just once - usually I was just moments away from figuring it out without help.
There is no time limit for any of the levels with the exception of the very final area that has a frustrating timer and requires you to use what you've learned along during your time with the game. It's generous though, and after a few tries you will know exactly what to do.
Highly recommended for fans of Portal and Superliminal (and with similar completion times), but imo both of those are better games than this.
