You are progressing nicely!
This game plays much smoother than your first. It's good to see that you are finding flaws and fixing or tweaking them. I'd love to collab with you on a game sometime....I've never been able to see my animations in that format! Cheers!
It's a fun and enjoyable game, with no noticeable bugs. the one thing I would consider changing would be the background. But other than that nice one ;)
I love the concept of not-straight enemy shots. On the other hand the background sometimes hide shots. SFBE.
Find it odd that I stop going left when I hit the number. But it was fun.
