Wow, top marks for creativity! The TV tutorials with the voice acting are so good, the powerups are very unique, and the game is pretty crazy overall. I felt the game very alive, and the metroidvania elements are on point as well. Also, Martia is great.
If there's any feedback to give regarding gameplay, is that it's very difficult to evade attacks on that scale, especially on bosses. I also agree with the comments regarding the dash button. Oh, and unfortunately the game crashed for me right after the battle against Massive Martia (I played the WebGL version).
Overall great game, one of my favorites so far, it's filled with personality. Excellent job!
