Neat! Works as expected, and I enjoyed the fact that it plays in terminal! I wasn't sure if you can shoot more than the amount of dice provided (4), but that's a game design decision I suppose!
You should be able to shoot with as many dice as you have ammo for, so if you have 7 ammo then you could roll all 7 dice at once. That would be a bit wasteful though ;) The plasma mine does have a limit of 4 dice if that's what you were referring to?
