It is a simple and very polished game. Your game looks perfect for a JAM. The asteroid hitbox seemed a little unfair though xd Nice work!!

Fun game, until it becomes impossible to win. Some of the asteroid spawns felt like they couldn't be beat.

The asteroid hit-boxes were a bit bigger than the sprite, it seemed. I think the hit-box should not cover too much of the back of the asteroid so you can slip past them easier and overall the hit-box should be a little smaller than the sprite itself.

The music would play on top of itself each time the level restart. By the fourth restart I was hearing a garbled mess of multiple versions of the same music looped on top of each other.

Pressing space to toggle your direction gives the player less control but I think makes for a more interesting experience because more thought goes into where and when to toggle instead of the second nature of up and down keys.

Overall, a decent entry. It would have been a lot more nice if the difficulty was a little more reasonable.

Loved the music and overall aesthetic! Really good use of a simple single game mechanic/interaction; that being said, I would have loved to be able to move the spaceship around.

The difficulty level is exquisite! It's a good minimal game that fits the pixel art style.

Beatifull graphics and sountrack, really cohesive.

Music is excellent!  So, it's like Flappy Bird, but with an alien?  I don't know about the theme.  Perhaps you could have made the fireballs human enemies instead?  The game is tough, Flappy Birds style controls would have made it easier.

Decent effort overall.

TOO HARD I HATE THE MAN THAT CREATED IT  I ALMOST LOST A FEMER FROM IT
