Hi JMB,
The SMG thing was actually a timer related bug. :) Good thing you noticed the rocket launcher firing only up; It should be firing into the direction you shoot, but home in if close to the target. It seems to be a migration bug because of upgrading the editor to a newer one (from Unity 2019 to Unity 2020). I've discovered the error and I just fixed it now.
At that moment does the score reset? After dying, reviving? Edit: I just accidently found out that it also seems to happen with player 1, if you managed to still hit an enemy after you just died. I fixed it now by not getting that score when you are dead/out of lives.
Also fixed the crocs getting out of the water... Again! :P
I will look if I can make player 1 the one who pressed fire first in the menu, if it isn't too much of a hassle.
Thank you again for telling me of these bugs, I will add you to the credits if you don't mind. ;) I will tell you here when the fixed new version is up.
Best wishes also,
Ededo
