The first-person dungeon crawling perspective is an interesting idea, but the fact you can only move to preset waypoints (instead of a grid) is a bit confusing. For instance there was a room where a path was clearly visible on my left, but I had to move past it and turn around to select it. Not being able to look around freely is also quite frustrating.

The biggest issue for me was that the interiors are very same-y and I just couldn't mentally map the space. I had no idea if I had already seen a room or not, so I was randomly selecting exits. It worked a bit better when I got outside, at which point it reminded me of the old point-and-click adventures of my childhood like "Rendez-vous with Rama". But then I ended up inside again and got lost.

I didn't see any paths requiring upgrades to my movement abilities, but I can see how you could turn this prototype into a metroidvania with for example a grappling hook allowing you to select a differently-colored waypoint above your head.
