I had an issue with lauching the game for all future players after extracting the folder rename the data folder to BangBangShootyShootyGalaxy_Data so the game can run.
I think the visual style and overall feel of the game is really good and with some more level design could be something more! Im not sure why but the player character is going to the bottom corner of the screen at all times so you have to always be moving in another direction to stay out of that corner and dying which I don't think is intended. I was a bit lost on what I should be picking up, I did pick up the large red orbs but had no idea what they did per say. I was able to pick up the shield person or the person that said they would be my shield but I immediately died after so I don't know if it worked or I was killed because I was in one place for too long.
Enemies tend to bunch up which seems fine just a big crazy to see like 10-15 enemies in a corner, I was able to make it to the 2nd level but had no time to see my score on level 1.
I enjoyed this game despite some of the issues I encountered.
