In Crystals, you play as a kid who accidentally traveled to another Dimension, which is being terrorized by a ruthless Dimensional Warrior. It's up to our protagonist to defeat Dimensio and restore peace in the Dimension, so that he can return back home.
In Crystals, you can:

• Explore areas based on elements such as fire, water, earth, electricity (bet you didn't expect this one) and sky
  
• Fight original enemies and avoid their attacks with a platformer-based system (don't worry you don't actually kill the enemies)
  
• Unlock abilities throughout the game by collecting crystals

Encounter special characters, fight against challenging enemies and intimidating bosses, live a story that you'll enjoy (how could you not like a game about a kid who barely knows basic math going to fight a bloody warrior who's able to tear apart a whole Dimension?)
