love the character and level design. the puzzles were engaging, I like the parallel reality vibe.
had the same issues with elements close to the camera blocking gameplay, and the fire puzzle door tree-clipping issue, I assume the trees were supposed to be gone for blue like alongside the thorn vines not just another color (circumvented by standing blue on the top of the slightly lower door-frame and jumping red off her head and over the top wall)
couldn't find a use for the big blue crystals.
I assume going through the door and being returned to the menu is the completion?
Nice work!
