About Marshmallow Marvin

Marshmallow Marvin is a 2D pixel art platformer in which you guide Marvin through dangerous underground catacombs to reach each level’s exit and escape. You jump between platforms, collect coins and hearts, and avoid traps, turrets and other hazards as the levels grow more challenging.

The catacombs

The dark, mysterious catacombs have narrow escape routes and increasingly intricate platform arrangements. Early levels introduce the main challenges; as you progress, hazards become more frequent and threats more densely packed. Reaching the exit calls for precise timing, quick reflexes and careful decisions.

Hazards and rewards

Spikes punish poorly timed jumps, while moving spikes rise and fall and require precise timing. Automated turrets lock onto Marvin and fire projectiles, so you must keep moving and react quickly. Coins reward exploration, and collectible hearts restore Marvin’s health.

You can take dangerous routes to collect more coins or play cautiously to preserve Marvin’s health. Planning your movements helps you avoid traps and enemy fire, and completing each level takes Marvin further on his quest for freedom.
