So first off, music and art were absolutely fantastic, loved those. As for the gameplay however, I have a few things I'd like to point out.
I think having the items not stand out so much in terms of their outline would help. I ended up finding most of them relatively quickly.
However, some items I found were impossible to find. I ended up searching for a branch for like 10 minutes and found it super small on the ground somewhere lol. Then I couldn't find the candy in the 3rd level after like 10 minutes so I gave up (I tried though!). In other words, put items in realistic places with the environment, and I think through having a few people play, figure out which items are very easy/very hard to find to balance things out :) Great stuff though, the feel of the game is awesome!
