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.
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.
The Grimvault is packed with deadly obstacles that will test your timing and precision:
Spikes that punish poorly timed jumps
Moving spikes that rise and fall, demanding careful movement
Automated turrets that lock onto Marvin and fire projectiles, forcing you to stay alert and react quickly
Treacherous platforms that require patience, timing, and control
Each new level introduces more complex layouts and a higher density of threats, pushing you to sharpen your skills and adapt your strategy.
The game features a retro pixel art style that creates a nostalgic platforming experience while reinforcing the dark, mysterious atmosphere of the Grimvault. Haunted tombs, ancient relics, narrow corridors, and cursed chambers create a tense adventure where every jump could be Marvin’s last.
Throughout the journey, you’ll constantly balance risk and reward:
Take dangerous routes to collect more coins
Play cautiously to preserve Marvin’s health
Time your jumps carefully to avoid traps and enemy fire
Explore deeper to uncover the Grimvault’s secrets
Completing each level brings a strong sense of accomplishment and pushes Marvin further into the cursed vault in their quest to survive its ancient dangers.
