Crystallo

Crystallo is a roll-a-ball adventure in which you guide Orbart, a sphere, through levels to collect keys and reach the castle. There, you must warn the knights about the wizard’s plan to kidnap the princess.

Levels and hazards

The game begins with only the first level and the credits unlocked. Collecting the key at the end of a level unlocks the next one, and unlocked levels remain available to replay. As Orbart rolls through each level, colliding with objects such as skeletons, barrels and coins increases your score. Spike traps and lava harm Orbart and add to your death count; the countdown timer continues after each death until it reaches zero.

Checkpoint pillows let you set where Orbart respawns if you hit a trap, rather than starting the level over. Some levels also contain hidden areas that can take you further into the game without playing through each level. Listen for audio cues and work out which portal leads to the hidden paths.

Versions and difficulty

Crystallo includes standard and HD versions, as well as two additional builds that support a PS4 controller. The standard version is designed to run on most PCs. The HD version targets modern computers with DirectX 11 or DirectX 12 capabilities and includes shaders such as flames enveloping Orbart when he hits lava; in the standard version, he fades out on contact with lava.

After completing the game, you can see your total score and deaths and try to beat your previous result. Winning also unlocks hard mode, which adds traps and reduces the number of coins and checkpoints.

Getting started

Tutorial text in the first level explains movement, camera rotation and other mechanics. A settings menu lets you adjust screen resolution, game quality, fullscreen mode, music and sound effects, and mouse sensitivity.
