Fun game! I find the pixel art in this game incredibly good, and I love Jin's sprite. He looks very cool, and overall the world is beautifully designed.
As for the gameplay: Personally, I find it a bit clunky. I would like to see 8-way movement and maybe iFrames for enemy projectiles while dashing.
However, I don't know how feasible that is to implement in an NES game, as I have never worked with NESmaker before.
I had a few slowdowns, but they weren't too bad. It could also be due to the fact that I played on an Anbernic RG353V.
I'm excited to see how this project develops or other projects from Video Games United! :)
