So fun I'm sad it's over.
It was like some crazy pixely UFO version of all those ninja games I used to play for hours on end. This only lasted me about 10 minutes though, and I wept when it was over. Can't give you crap for length though, since it's a casual game with a score system. However, if you do happen to create a sequel... maybe some bosses, more types of enemies, more abilities, but without making it over complex would be my cup of tea.
The music is fitting, the graphics are fun to look at, and the gameplay is simplistic but enjoyable. MORE!
