The pixel art is gorgeous, I particularly love the effect when a ship explodes. The parallax effect of the stars scrolling works really well, although I did find it difficult to distinguish the bullets from the starts. The game could definitely benefit from showing the player their score and health, but overall a really solid game that I definitely enjoyed!

A visually impressive game with some tight controls. Challenging, but not to the point of annoyance. Well done for having only a single control and having the character auto-fire. Game is easy to download and install, but is there a more user-friendly way to do something similar?

I had a problem with visual clutter. The stars flying by was nice, but it was quite hard to tell where my and the enemies projectiles were. Being able to exit the game or restarting once I had failed would be greatly appreciated and contribute towards user experience. Finally, there doesn't seem to be a difficulty progression, perhaps you could make enemies spawn more or less frequently based on score?

Overall, a solid submission that with some polish and expansion would result in a very engaging and exciting game. Well done.
