Great game! I'm not a huge fan of pixel art 8 bits, I'm from 1995, and my nostalgia leans towards 32 bits. However, the game is beautiful, especially the H art style. The gameplay is simple but excellent; the intentional 'heavy' feel of the dash effectively simulates the limitations of games from that era. The boss fights are well-executed, and the final boss is quite challenging. It took me 30 minutes to defeat it.
I'd give it an 8/10.
