Hey Axi,
The rules/actions for shooting was added, but it made the game too easy.
I was thinking about how to still use the shooting mechanic but also keep it challenging and engaging, but 3 hours is not a lot of time, so i scrapped the whole shooting for now.
Maybe after the voting is complete i can revisit it and look at implementing shooting (with a limited ammo as you stated) and also speed up the rocks, this is something i only though of after submitting it, if i can speed it up slightly every now-and-then, it will make it a bit more challenging.
Thanks for the feedback, much appreciated
