Damn.
It looks great and plays nice. I love the health crate ships idea. Enemies feel slightly bullet spongy. It would be nice to see visible damage when enemy ship is about to be destroyed - that would slightly help with picking target when there are lots of samey enemies.
Gameplay is definetely solid and fair. I managed to win with 1 health point through 2/3 of the second level.
Is it compatible with brutal doom?
