How to Play

Getting started with Sebastian’s Quest is easy, yet deeply rewarding! The game is fully browser-based—just load and play. You control Sebastian, a plucky adventurer, tasked with pushing gems and locating the elusive cheese in each level. Movement is handled with the arrow keys, allowing precise navigation through maze-like rooms. To interact and move gems, use the X and C keys; X is your main action button for pushing gems, while C opens up secret passages or triggers unique level mechanics. If you prefer a gamepad, the controls are perfectly mapped for a comfy, console-like experience.

Your primary objective is to cleverly manipulate gems, sliding them across the floor to clear paths or activate tricky switches. Levels are intricately crafted, blending logic puzzles with exploration. Always be on the lookout for hidden nooks—some cheese is tucked away in the most surprising places! On mobile, touch controls are intuitively designed, ensuring smooth gameplay wherever you are.

For beginners, start by exploring every inch of each level before making your moves. Sometimes, the solution isn’t obvious—take your time to plan each push. If you get stuck, don’t worry—you can always reset the level and experiment until you find that perfect move. Progression is saved automatically, so feel free to test new strategies without fear. Let the catchy retro soundtrack and pixel visuals draw you into Sebastian’s quirky quest for cheese—adventure truly lies at your fingertips!
