Wow, you found an optimisation for firing faster... multiple fingers for multiple keys! I didn't think of that! haha! :D
You did pretty well indeed, my friend.. most impressive! :D
The aliens will absorb the shot if shot inside, and the max shots on each alien is 10, so they won't go down any faster after 10 shots, they just absorb and block. The "shoot more to bring them down faster, else they block line of sight" was part of the plan.. but all the aliens squished together part wasn't. Especially those BBBs, they can be troublesome! I was going to optimise the spawning locations, so that they don't spawn so close together, but you know how game jam 48 hours go by so fast! haha!
Thanks for playing, and for the feedback! :D
P/S: BBBs, I like that name!
