Controls and visuals were nice in this one, the music also fit the theme of the game well. I would have hoped for a high score system or something to see how well I did compared to my other runs. Also the hitbox felt somewhat big, and it would have been nice to have some kind of audio cue or visual feedback of when the dash has came available again. Also some random elements in the patterns would take the game to a next level, since at least for me it seemed that the patterns came always in the same order. I did like the look of the boss very much, it oozing around and all, so cudos for that!
