Sure! I think the game has a solid base and some good potential, especially if you keep polishing it.
I did notice some issues with the resolution and/or how the assets are displayed. Some pixels appear larger than others, and even the main character seems to have a few diagonal pixels, which I believe may go against the jam’s visual restrictions.
I also had several moments where my bullets passed straight through enemies, especially when they were near the top of their jump or still moving upward.
Aside from that, I think that with those details polished and a faster, smoother sense of progression through the stages, the game could become much stronger. Nice work overall!
