Great pixel art it so cohesive and you have your style, amazing. Just a few things that would make the game better and then some hits that... well points just for me.
- The sound of the laser is too high maybe down a little.
- The movement of the ship is to fast and the area is to small, I get that this is for the feeling of the theme but makes the game hard to play (In the bad way).
- Maybe the face of the character can make faces, like when you get hurt.. he is in pain, or when you pick up a power up... I don't find in my playthroughs.
Like I said before this is just my saying how I do thing, because the game is awesome and I like to play it more. Nice job.
