Played all levels :) Great effort for a first Godot game. Implementation wise I didn't really encounter any issues. As far as game design goes, there are some interesting options presented: more money is more weight, the general ability to carry more than one item, crouching mechanic which you can't use with more than 1 item. But in the end the puzzles don't really use it much, which was a shame because I was looking forward to being challenged a bit more :)
