Why are the citizens standing on the rooftops anyway! Go to a bomb shelter or something!!!
Lol, but anyway, great game, I only feel lucky that you gave me a small screen so that I could move fast enough. The Gameplay is very good, trying to fire beams and move fast enough to save everyone is a true challenge. The animation makes it better, you know one of your shields are down because you hear the signature "Ahhh!!!" and watch people fly across the screen. No obvious glitches that I've found, and even thing seems to work perfectly.
However though, the music does get annoying after a while... It sounds like one of those old retro games and it repeats way too often. The art is surprising lacking though... it would do well in an animation but for a game its merely ok... the lines need to be polished a bit with sharper colours, like the simple graphics of Diepix Arena 2.
I also sort of agree with TJCom, the game could use a pause button but since the levels are so short its not as necessary. So to recap, great game, but needs slightly better graphics and suited music.
