Thanks for the amazing feedback! I agree 100% with your list of "wants". They're all great, and made me kind of excited to implement the after the jam :)
I really like the idea of more canon balls fired at different heights. I think that would beef up the defensive element of the game and make the canon balls a little more significant.
Different ships and speeds is a great idea too. One idea we tossed around, but ran out of time, was to have ships at different heights. Like a hot air ballon that you would have to reach for, or hit another ship into it.
I also don't love the "wait for two ships" gameplay. Question, Do you think it would be better if the tentacles didn't go off screen?
2400 points is currently the highest posted score. (I was told by the programmer one of his coworkers hit 2800, but haven't seen any proof lol)
