Thank you! We updated our description to match your feedback so hopefully other people don't get confused there either!
When we revamp things to try to make a better version of this (if we do), the timing of the throwing mechanic is something we'll definitely be looking at. We'll have to hit some balance between feeling like their throwing when they want to (on mouse click) and visually when they should (when the character's arm is extended). We couldn't quite get it right in time for the jam, but hopefully that's something we can figure out for the future!
We will definitely let you know if we die-cide to keep working on it!
