Featured on gamescom 2020 and long-awaited, finally, it is here! German Publisher HandyGames and French Studio Seed by Seed are unboxing the release date for their family-friendly couch-coop 3D platformer! Pile Up! Box by Box will take you on a trip to cardboard world, where you help the Boxlings to solve fun environmental puzzles alone or co-op with up to four players! Pile Up! Box by Box is coming to Steam on March 18th, 2021. The demo will be unavailable for download until after release, because it is outdated and doesn't represent the quality of the final product. Post release, we will deliver a new, updated free demo that will let you test the game in all its glory. We're very happy with how the game turned out and can't wait for all your feedback. Thanks for reading!
