What worked:
It's an interesting idea. I like the thought that you exist in a world where every creature is fighting for light. It could go in interesting direction if you decide to continue this project.
What didn't:
The enemy fire rate may be a bit fast with the size of the player.
I found the best way to play was to wait out the enemy attacks until they couldn't shoot anymore. You may want to give the player more strength or ability to deal with projectiles so this is only an option instead of what seems like the only way to play.
Bugs:
Didn't find any.
Great job! (score 6865)
