Kumoon is Finnish for knocking over boxes by ricocheting your projectiles around the rooms. Mixing a shooting-gallery with billiards, platforming and puzzle-solving.
Besides taking potshots at boxes, there's a fair smattering of platforming and wall-climbing. An aggressive default movement speed enables you to make leaps over large gaps. So for those with sturdy VR legs, you can play as wildly as you wish. More sensitive players are given a half speed option to take things a bit slower, and using the analog sticks gently allow you to go as slow as you like.
The levels are all unlocked by default, so players with low tolerance for freedom of movement can pick and choose which levels to play.
