First and foremost, I love the art - the scenery is so detailed and the characters' and items' sprites look amazing.
The intertwining stories were pretty fun to unravel, and carrying your items between worlds is a fun concept that was taken advantage of in several different ways throughout the story, making for quite an enjoyable experience!
My only gripe is that it was easy to get stuck. I managed to gather what I can only imagine to be most of the items available, and ended up just clicking around, wondering if there was some interactable element that I was missing, or if there was a glitch that stopped the troll or scared boy from continuing their storylines. To that effect, some guidance, whether that be outlining interactable elements on hover, or a hint feature when stuck, could be something to consider in the future.
Great work on your first submission as a team!
