Downloaded the game this friday through the itch.io desktop app. It should be the latest version. The pick up indicator is there.
Remembering some other stuff right now.
I also got stuck in a tardigrade corpse. Couldn't move until it was completely harvested.
Filling the water bottles is also a little difficult sometimes. Had to move around the well and retry a few times before it would allow me to fill.
Chased an antilope into the river. It kept moving back and forth but didn't get out and didn't run away when I got close.
