sigma balls never occurred to me hahaha
The ball beings getting stuck is a side affect of me not using pathfinding and just making them move straight for the player. I'm working on some fixes and improvements and A* is on the list. I made an A* system a few weeks ago so I just need to find the time to port it over into this game, probably tomorrow. The shotgun should also feel a bit better too with the update since I'm fixing two bugs that cause input latency and dropping. Glad you liked it though, I'm hoping to apply the reload idea to more guns in another game.
Thanks for the feedback!
