I was really impressed by how good the puzzle design was in this game. I thought that the puzzles were very well thought out and I would love to see what this concept could expanded into.
The only thing that held this back for me was the gameplay, as there was a lot that seemed either "finicky" or inconsistent. I often found it really hard to successfully pick up items and the throwing would occasionally miss it's target for reasons that felt like they were outside of my control.
If those issues were ironed out I think that this would have been one of my personal favorite games of the Jam.
All of that said, you did a really great job on this, congrats! :)
