It's a very interesting concept, although there's a few things you need to improve upon. Such as, a menu and music. There's menu tutorials online, and you can get Copyright-free music or sound effects pretty easily. Also, the game is very glitched, sometimes the sprites don't load in right. Also, I don't know if this is intentional, but the arrow keys just make you fly? I'd also recommend getting better graphics, such as a pixel art style. Oh, and the really huge thing that you need to get is a checkpoint system, I made one mistake then had to retry everything, which is frustrating to the player and doesn't make you feel like you want to continue, escpecially when combined with the rest of the game. And finally, the game need to make you feel something. The ending has no impact, and the lack of sound really doesn't help. I'm excited to see how this game grows over time, this has potential.
