Super cool game! I really enjoy the patterns and the visual impact of the disco level. What I love most is how theatrical your bosses are, and how ingrained and important the dash mechanic is in these fights. I think the most "bang for your buck" type of adjustment for this game would be to add a strong sound effect for when the player is hit; some extra impact there would make this game truly addicting, and I think would add an extra motivator for the player to try again. Overall a unique and beautiful experience - thanks for making this!
