Oh my goodness this is incredible!
I was checking out all the NES compo games and I couldn't stop myself from playing this like 4 or 5 times before moving onto the next game.
The art and sprites are all cute as heck, and everything feels vibrant and clear. I absolutely adore the aesthetic of the game, and it looks wonderful and plays super smoothly even with all the projectiles!
The music is one heck of an earworm, too, I couldn't stop bobbing my head. And of course, as a game itself, this hits a sweet spot for me difficulty wise and it's nice to know you'll be adding multiple difficulties.
Much love on this project - very much looking forward to the full game, but also just want to express that I loved the experience provided by the demo, too!
