Lots of fun, nice work! :)
Things I liked:
- Combining weapons is fun
- Dodge feels great
- The music is fantastic
- The title screen and environment pixel art nice
Things that could improve:
- Some UI indicator of what weapons you have
- Iron out a few bugs, I got shoved against walls and killed often
- Tightening the movement, maybe the sprite animation could be a bit faster
Overall I think I had the most fun when I felt like I was zipping around and being a badass dodging bullets. What do you think about having the dodge give you some invincibility frames to dodge through bullets and enemies?
