This is pretty unfinished but I think it has potential. I know this is a demo/concept, but having to reset the game every time I died (because there wasn't even a respawn implemented) was a bit annoying.
I like the pixel art for the stage tile-sets but I think the smaller/fodder enemy ships could have their designs/look improved.
What I enjoyed the most was the music. Whoever you have doing the music did a real good job. The compositions are nice and the style is reminiscent of like...PC Engine game soundtracks? It's very cool.
