Looks like you can walk on walls?
There also appears to be some platforming elements.
How do you get out of the spawn point, doesn't seem to be any doors that I can see?
Looks like it has some elements of regular FPS games, such as King of the Hill or Capture the Flag.
(Edit)
Forget Capture the Flag as it doesn't look like their will be teams or how can you tell your friends from foes?
Talk about an amazing first post!
Updated list:
1: VizionEck has spawn rooms instead of spawn points. Both friends and foes spawn in the same room.
2: Yellow power-ups are found in the game. Collecting them increases jump height.

VizionEck is a platformer at heart.5:
Rangers may have different relative gravities. Your enemies might be on the ceiling or walls, not just the ground.6: Instead of displaying health with a HUD, health is displayed by the brightness of a Ranger's outlines. This allows you to know your own health as well as your enemies' health.

8: Rangers have the ability to generate charge blocks above them. Charge blocks act as shields and can defend players against enemy attacks. This makes lower relative positions valuable.

12: When a Ranger is low on health, they naturally blend into black backgrounds. This gives them a stealth advantage.

15: Spawn rooms have 24 cubes, but not all of them are Rangers. If a player doesn't move, it's impossible to tell them apart from a regular cube.
Your other points aren't on the list, but I can comment on one of them.
Each spawn room is slightly different depending on the map. With the one shown in the announcement trailer, the only way out is up.
