Here is a video of a full playthrough of Vertico, for those who got stuck.  Note the video might spoil the game a bit if you haven’t played it yet:

Vertico is a 2D isometric “three degrees of freedom” shooter.  Dive beneath the ice and fight creatures while moving in any direction in 3D space, navigating a vertically-oriented coral reef.

I’m really, really satisfied with how this one came out, so please give it a try if you haven’t already :]

Timelapse will be coming eventually for those interested.
