Extremely well done game! This alone is a great tutorial, an often overlooked thing in game development is teaching players how to play something in a safe environment that feels fair and clear, nailed it. Music and especially the sfx are great. More color could make things more interesting, but also, coloring important things (like the photo objects) is a good contrast to teach players also, so maybe ignore this one, the shadow of the player is hugely important for the platforming, glad it's in there. Great job!
