Ok so Im on your Linux version, and Im already noticing some wonkiness in the controls.
For starters, the grab/throw mechanic was really hard to figure out, as was how to drop objects. A written tutorial with signs would be good
Second, the character slides around when moving waaay too much, leving for frustrating parts where you fall all the way down to the bottom.
The projectile bounces are infinite, meaning that it bounces around for too long and goes to who knows where offscreen, making it impossible to track the object. I'd suggest limiting the number of bounces/capping the distance travelled.
Lastly, controller support. Explicitly defined twin-stick controlling is badly needed due to the whole aiming where you throw bit.
And here's the log output, if thats useful: https://pastebin.com/sDHVz6Y2
