Man, lovely art, it's so vibrant and colorful, it simply looks astonishing. Love the lore and the cutscenes, it's so well put together. Love the lobby, could spend the entire day in it, so well designed.
Combat is fun, I think you were inspired by Enter the Gungeon. I feel the main pistol should have a slightly faster firerate and the bosses are quite tanky, I think you should lower their health amount.
Like wow, this game is truly impressive, I see lots of love and passion behind it, I hope you plan on developing it further because this is great.
