Thank you very much for for the feedback and playing
When testing I found lot's of ways to exploit the game and didn't really think of how stopping these exploits would affect normal gameplay, I found staying still and spamming especially over-powered. Once the jam is over I might add some difficulty options like bumpers on the side of your ship to stop the guns sliding off (like I originally had) and less often and weaker side lasers. And thanks for the kind words about the presentation. I spent far too much time on it! I had thought I fixed the enemies reaching you before you can see them but evidently that didn't work. I agree with most of your points and like I said will try to fix them post-jam.
Thanks again for the feedback!
