At first, I didn't quite understand how to play. I was even winning, but I didn't grasp *how* I was winning. It was only over time that I figured things out and started devising specific tactics for different opponents. The gameplay concept and the interpretation of the theme are very interesting. The visual style and color palette are very pleasing—though the way defeated enemies fly off-screen does clash slightly with the overall style)
I think the idea behind this game is worth developing further after the game jam. Good luck!
