Oken

General guidelines:

• Avoid constant user death
• Make the player jump and evade as much as possible
• Create interesting "arenas" and populate levels with them (2-5 per level)
• Guide the player through the level using auras
• Prefer water over holes
• Populate levels with spikes to restrict players movement and add challenge to the game
• Create areas that require the use of the wall sliding ability
• Use Slippery areas to prevent the player from wall sliding and to delimit the level (boundaries)
