Teslagrad

The game communicates without words.

The player moves inside the tower which can be freely explored (but, as it is a tower, the general direction is up and there are not many branches in width).

To progress, the player needs to use special abilities to solve puzzles which are all based on magnetic fields: many objects have a magnetic field (red or blue); objects with different colours are attracted to each other while objects of the same colour are repelled.

The player has gloves which allow him to change the polarity of objects.

During the course of the games, more abilities and gadgets are earned, e.g. a cannon to change polarity over distances or a short-distance teleport to pass deadly currency unharmed.

Those are used to reach new parts of the tower.

The puzzles are mostly embedded in platforming challenges which require pixel-perfect jumping and fast reactions.

There are also a few boss battles.

Teslagrad for PlayStation 3 is currently worth €45.36 loose, €22.30 complete in box, and €20.22 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Teslagrad has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Teslagrad, loose is €45.36 and CIB is €22.30 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Teslagrad is currently worth €45.36 loose, versus €50.44 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
