Thanks for playing! Yeah the jumping definitely needs some work, as for ammo your pistol has unlimited you can swap back to it with Q id you've picked up a primary weapon. There's a hidden mechanic to get more ammo/health which is having your body hit an enemy as you tether back, every 5th kill gives you 1 health and every other gives you ammo. The RNG probably needs some tweaks to give you more primary weapon ammo boxes though
