Great visual and mood, I found it very fun to fly around specially in tiny spaces such as the drain and the keyhole, the steps were also easy to understand, nice work on the sound awell.
I didnt encounter any issue with item clipping in this game, I have encountered this issue in one of my past jams and here is how I fixed it. The cause was a relatively small collision shape, I solved it by going to Project->ProjectSettings->Physics->Common and multiplied all the values by 2. Im not sure if it will work for you or if its a healthy fix but it worked for me.
