Finally an indie metroid-vania that takes advantage of it's movement with interesting encounters and terrain.
The tether is very versatile and all upgrades all work towards giving you more freedom when using it.

The level design and bosses really makes you have to think about how the tether works and I feel like it was properly explored as a platforming mechanic which can be quite rare to see.

The map is truly open and doesn't give you an illusion of freedom like most metroid-vanias do.
