The first thing I said when I made the trash hole was "People are going to jump in this thing", and judging by the comments, literally everyone did XD. I should've put a secret down there or something.
Yeah the proximity shine would've been a good idea actually! A lil indication that "hey you're supposed to pick me up". And I wanted to put a lil icon near your inventory that indicated throwing and had "f" but never had time.
I do agree the gameplay loop felt a bit tedious after a bit, maybe some new mechanic tied in with it could've kept it interesting. And in terms of the song, yeah I had the same thought. I wanted to have the song on the menu and play one loop while you start the game, and then have a more ambient sounding song play after that, but never got around to it.
Thanks for playing and for the comprehensive feedback :D
