Well, I managed to get one of those medals. I admit to being really turned off by how hard it was. It was especially the part with the boss. I think it was a boss? It was hard because he kept making more enemies. He even himself wasn't that bad, just the more mayhem he created!
It's still a very original design. I really appreciate how good the graphics are. You have to time everything with this game. The projectiles aren't as fast as the enemy ships. The sounds are great too.
