Ok I see what you tried doing here and I love it 😉 I see it’s your first game so good job for that, welcome to gamedev 👍 !
The needles need a minimum of impact (1200% of 0 is still 0 :D ) otherwise you can just shoot eachother and nothing happens. Loved that the teleport works on all directions so you can have litteral dragon ball fights!
Local multiplayer is a great idea, it can make really fun games! Keep on going!
