Compare Marshmallow Marvin: Grimvault prices across trusted key stores and find the best deal. Developed by Jolly Lobster Interactive LTD. Published by Jolly Lobster Interactive LTD. Released on 4/8/2026. Available on PC. Genres: Action, Adventure, Casual, Indie.

A pixel art platformer that respects your reflexes and your time, with traps that punish sloppiness and a deliberate pace that lets you breathe between jumps.

I spent enough time with Marshmallow Marvin to know this isn't another hollow auto-runner. The pixel art holds real craft, each cursed vault and haunted tomb designed with clear sightlines so you see the danger before it kills you. Precision platforming sits at the core, but the turrets and trap timing reward patience over button-mashing. Coin collection gives you reason to replay routes without forcing 100% completion on your first clear. Grimvault lands somewhere between 'good at weeknight gaming sessions' and 'short enough to respect your attention span.' Controller support feels natural, and the achievement slate suggests the developer knows their audience. If you're after a challenging 2D platformer that doesn't outstay its welcome, this one's worth the vault descent. Kai, Scout Team
