This is so much better than the score would suggest. Far from an average shooter - it's varied, original and great fun. With some of the best graphics around.
I've followed your work over the years and it was nice to play a kind of callback to all the great characters you've created.
Could suggest a few things, the movement was a bit mechanical, some acceleration and deceleration would be nice. And putting comments with a game will always help, surprised that you didn't.
Keep the games coming, you're one of the best.
