Exploration platformer with some super cute pixel art and a really good learning curve in this first, expansive demo level alone. I'm already sold on the full version and I didn't even finish exploring everything that was in there, I'm pretty sure. Glad I managed to figure out what game it was in the banner video for the Steam NEXT Fest despite it showing for like three seconds and not having any indication of game name there.
Apparently the devs from this worked on Kamiko, which I've had sitting on my Switch for a while. Guess I should hit that up soon.
