About This Game

Guide Marvin Through the Grimvault

Enter the cursed depths of Marshmallow Marvin: Grimvault and help Marvin survive a haunted underground vault filled with ancient traps, deadly turrets, shifting passages, and perilous platforms. In this 2D pixel art platformer, you guide Marvin through increasingly dangerous chambers while collecting coins, restoring health with hearts, solving platforming challenges, and uncovering the secrets hidden within the Grimvault.

Gameplay

Your objective is simple: reach the end of each level and survive the vault.

As you journey through each stage, you’ll leap across crumbling platforms, avoid deadly hazards, dodge enemy fire, and collect valuable items along the way. Coins reward exploration, while hearts restore Marvin’s health, giving them a better chance of surviving the dangers ahead.

The early levels introduce the core challenges and help you get comfortable navigating the Grimvault’s dark corridors. But as you progress, the vault becomes more dangerous. Levels grow more intricate, traps appear more often, and success depends on precise timing, quick reflexes, and smart decision making.

Every step deeper into the Grimvault brings new dangers, ancient secrets, and a greater challenge for Marvin to overcome.

Spikes that punish poorly timed jumps
