Read full description

Pile Up is a cute physics stacking puzzle game where everyday objects become a wobbly tower of chaos. Drop, balance, and stack funny items across playful worlds like the kitchen, office, beach, and bedroom. Each level gives you a new set of objects and a new challenge: reach the height line, place every item, survive moving obstacles, handle wind, and use heavy or sticky objects wisely. Every object has its own shape, weight, bounce, and personality. A pan can steady your tower, a jam jar can help pieces stick together, and one bad drop can send everything tumbling. Features: - Fun physics-based stacking puzzles - Cute cartoon objects and colorful worlds -120 handcrafted levels across 4 worlds - Different object shapes, weights, and materials - Height goals, wind, moving obstacles, sticky objects, and heavy anchors - Easy to play, tricky to master - Short levels perfect for quick play sessions Build carefully, laugh when it falls, and try again until your stack reaches the top. Can you pile everything up without making it all come crashing down?
