Dashing and Healing use the triangles,use it offensively or defensively, it regenerates when you shoot at enemies

Can wall bounce if near a wall, just press the "Space" key. The triangles at the bottom center are the resource for dashing and healing. 

Sometimes the enemies get stuck on walls due to some NAVMESH issues, if you feel like you have killed everyone but can't progress, try to look around in the level for an enemy stuck around objects or a wall!
