Wow, thanks! Definitely, the plan was to add some more puzzles, but we just ran out of time.
We wanted to make a puzzle where you have all the walls rotaing in unison, but rotating 90 only when you hit the wall. So you have to rotate wall A to get wall B to rotate, and get other objects to rotate, and so on. Unfortunately we ran out of time.
We also wanted to add a variety of bullet spread patterns to the enemies to give it more of a bullet hell feel.
I will check out your game too!
