Wow, just wow. This might be one of my favourite games so far. The retro arcade style, the amazing well designed bullet hell patterns, the beautiful pixel art... I liked almost everything from this game and even replayed some of the bosses. It's so addictive and polished that made me forget for a moment that it was a jam submission. I would just say that the theme implementation wasn't really strong, but despite that, I give it a 10/10, amazing job!
