About this game

Some walls are meant to be solved.

Before you stands a wall of cards hiding a single illustration.
Clear the mini-game on each card, and the wall disappears piece by piece, revealing more of what lies beyond.
When the final card is gone, the hidden illustration is complete and saved to your gallery.

impenetrable-ft is a collection of mini-games that challenges your logic, memory, observation, and reflexes as you make your way through the wall.

Take on One Stroke, First-Person Maze, Slide Puzzle, Memory Match, Word Search, Flow Connect, Water Sort, Spot the Difference, Rhythm Tap, and more.
Every one is short enough to finish in a spare moment. Peel the cards away one at a time.

Collect pieces from the gacha to unlock new stages.
Return to your collection anytime in the gallery, where you can admire completed illustrations and view them from every angle.

Solve one, and you'll want to see what comes next.
Clear the next card and discover what lies beyond the wall.
