Amazing! I loved the idea, but I personally didn't like that you could lose your shield. It feels like it becomes a completely different kind of game when that happens. I also think it was kinda confusing that certain enemies were one color, but their bullets were the other. I think it would be better if all of the colors matched so that the player would be able to react better. All in all a solid entry and a great foundation to build off of. Nice Work!
