Loved it! I had so much fun playing. I couldn't quite beat the final boss. I got so close a couple of times, but it only made me want to keep trying. The music was fantastic and really kept the energy up!
I also think the game has huge potential as a roguelite. The core mechanics are already a lot of fun, and with some progression and replayability, this could become an even bigger gem than it already is. Great job!
