What lies beyond the world we know? Is there another reality waiting to be discovered?
Enter the Alter World , a mysterious parallel reality where the rules are different and every step brings new challenges. Inspired by Stephen King's The Dark Tower , Alter World is a 2D platformer built around a unique mechanic that allows you to switch between two realities at any time to overcome obstacles, solve puzzles, and progress through the adventure.
Each level requires quick thinking and careful timing as you learn when to shift between worlds. Combined with its hand-painted visual style and atmospheric soundtrack, the journey offers a distinctive experience from beginning to end.
Unique reality-switching gameplay mechanic.
10 different worlds to explore.
Puzzle-focused platforming with fast-paced challenges.
Keep moving through the Alter World, search for your friend, and be prepared for the unexpected.
