100 Doors: Parallel Worlds is the brain-bending follow-up to the popular escape-the-room game,
Use your head to get out
100 Doors: Parallel Worlds is made up of 100 levels, each composed of a room with a door that you need to find out how to open. You can only move on to the next room once you've opened the door.
Puzzles involve cracking enigmas and codes, finding and using objects in a certain way, tilting your device to reveal clues, etc. A word of warning - the puzzles in 100 Doors: Parallel Worlds are tough. Very tough. In fact, after level 12 it becomes so hard that you'll be reaching for Google for help in order to ease your frustration.
Moving around the room
The game interface in 100 Doors: Parallel Worlds isn't as easy to move around as it could be. For some reason, the developer of the game has favored a slide-to-zoom bar, rather than the more traditional pinching touch gesture, which is quite irritating. Other control gestures are used to good effect though, like shaking the phone to crack rocks, or rubbing the screen to wipe away dust and reveal hidden objects.
The graphics in 100 Doors: Parallel Worlds are pretty ordinary. When zoomed-in fully there's a bit of blurring and pixelation, and dragging your finger to move the room around results in jerky animation. The inter-galactic background looks nice, though.
If you're a proficient logic puzzle player then 100 Doors: Parallel Worlds will bring you lots of fun. For the average player, though the puzzles are just too difficult to solve.
