This game has some real standout stuff. The backgrounds are really good and the music is great. My biggest critique is the controls. It took me a little while to figure out Ctrl was to shoot. That and having space as jump just wasn't what i was expecting for an NES game. There is also a part in the second level where I dropped down to get some collectibles and there wasn't a way back up. Had to jump off and start the stage over. But I liked your game a lot and I can see you spent a good amount of time on this.
