The concept idea is really great, turning the 3D mesh to a 2D one to help navigate through the level is great, though locating these places where you squeeze yourself through was quite tough with the level environment being so similar, I think adding a place hint for level required areas is better but not for the hear areas
The heart collection addition is a great choice, they’re well-hidden and it’s satisfying to find them
Got stuck on the second level :D, I really wish finding the squeezing areas was easier, great game overall
