Retro
It was a nice game and quite fun to play. I loved killing the enemies with the mega cannon. The graphics were very good. Lots of people say the graphics are bad but they are meant to look retro and making things look pixely on flash is a hard thing to do. The sounds suited the retro style and you've created something that looked like it was on the NES or something. Overall it was good enough with nice powerups, quite good gameplay and OK boss battles. I'd rather have a sidescrolling shooter but I suppose you've already done that with Wasted sky, Project Eddy and in DomoKun's angry smashfest. A very enjoyable game, well done!
