Was a pretty good game. Going to keep playing it though :p Got Survival and the Last bonus round + boss round to S rank then I'm all done.
Do you think you could add a difficulty modifier in any way? For example, Have Positive cheats which will raise your score. These could include Enemies fire Double bullets, Enemies have 33% more hp ect ect.
I didn't notice the 20 level no health Medal when I started.. Got 2 more missions to do at the moment then I'll of S ranked it all :D that makes me happy.
