This one was funny! You took a cool approach to the jam's theme. It's fun to keep trying and trying just to see what crazy enemy is coming to destroy the world this time. That Star Wars song took me by surprise. It's great that you kept a ratio between player's upgrades and enemies difficulty.
I think some obstacles are a bit unbalanced in comparison to the player's speed. It's creative to limitate the movements to the shoots you do, but at the same time some enemies aren't made to be destroyed under that conditions properly. Try to keep a better balance with difficulty.
You nailed a great charisma point, very well done!
