Wow, this is so sick! Love the strong art and sound direction, including the boss themes tailored to each enemy - the dog one made me laugh. I was unfortunately unable to land a single hit on the 9hp final boss, but i think that was a skill issue haha. I think my only real feedback is that by the time i got to the dragon bossfight, the soundscape was a little crowded with the open/close, all the attack directions, etc. I was also sometimes confused why i took damage, if my input was too early or too late or if i made a different mistake. Overall though, I think you really rose to the occasion of making a complex, challenging game that can be played with no visuals. My favorite part was probably the first dragon fight, I smiled ear to ear when i heard they could invert the polarity of inputs. Such a creative idea, and it was really delightful to have that mechanic ome back in the final boss. Great job!!!!!
