I really liked the ghost designs, it was fun to see who you put in the game! 

A lot to like here. Loads of charm and character, cool concept, nice visuals (especially the bullet effects) and good music. 

I did find that because the levels are fairly large scrolling areas and I don't need to aim to attack the boss, all my attention was on the bullets and the rhythm window; this meant it started to feel a bit like I wasn't really "fighting" the boss so much as playing a rhythm game while dodging bullets. Not exactly a criticism, just something I noticed. It would be great if the rhythm game part of it was a little more varied and integrated into the music of the game too. 

Again, what's here is really cool and impressively done though!

I didn't expect a rythm style boss rush game! The art and sound are great, and the bullet hell style boss design is extremely polished. Though I felt the difficulty of keeping the rythm going a bit high with all the attacks flying at you, it was still a really enjoyable game, great job!

A very beautiful game! Great music. But the gameplay is very difficult. It's hard to keep track of movement and getting into a rhythm.

the game looks good, but in my opinion the mechanics with notes are not very suitable, because you need to follow the bullet hell and because of this you often don’t get on the beat, and if you follow the beat, you very often receive damage and if i wanna use dash i often dont get in beat.

really cool game, everything looks and fits together nice , I  actually found it a bit difficult, I couldn't get past the first boss, I kinda wanted to shoot the big green bubbles to get past lol  , now I don't know if cause I don't actually game often or not lol, still a well done entry

The attacks felt a little out of sync/tune with the music, but overall the art was awesome, the boss patterns were killer, and it was a very polished entry!

Wow. Just wow.

I don't understand how the ghosts work. The music isn't in sync with the attacks (which is HIGHLY disturbing). The game is a bit too easy for me. I just attacked and ran around and I killed all three bosses.

For the rest...
- excellent music
- excellent controls
- excellent art
- excellent... fun !

GG for this entry, it was loads of fun.

Cute visuals and nice music! Love it! 

Dynamics is nice, I have fun with it! But there is disharmony between how shot sounds and music sounds, they don't go together this makes overall experience a bit off. Otherwise this is absolutely nice.

Really like the music and the boss design, The game feels very polished, well done!

Very good game, I really like this concept and I think you executed it very well. The mechanic of exchanging your music to get different abilities and recharge ammo was very good, but the ability where you can place down a shield to hide behind is by far my favorite part of the game. I never would have thought of that in a bullet hell. Though I haven't played a lot of them so that might already exist, but if it doesn't, good job. 

Probably the best use of the theme I've seen so far, very polished game too

Cool concept, I’ve always wanted to play some kind of rhythm based twin-stick! It’s a little strange to hear the musical note get played in an unrelated key while the background music is playing in a different key. It might be worth pitching the ‘shoot’ musical sound effect up and down based on the background track to make this a bit less discordant. Also, maybe it was just the web version, but I felt like the shooting rhythm didn’t always match that of the music.

I ended up dying at the 3rd boss unfortunately, but I got close to beating it! I liked the different spirits, I was pleasantly surprised that they all had really different effects (especially the healing spirit). Nice job! I like the gungeon-inspired art style too.

I remembered Enter the Gungeon when I played it. The game is difficult but that's normal for a bullet Hell. The third boss teleports to your position causing you to lose life unfairly. Otherwise very good game. GG :)

Wowie. I really really liked this game. It looks great, the music is really good (really loved the voiced over track), and the gameplay is fantastic. The inspiration from enter the gungeon is clear, but I think it does great within that framework. This really felt like a demo for a game that a lot of people might pay for.

Overall first impression, very high. So far favorite game I played today, which isn't saying a lot, but I think this has some depth and is interesting. I will come back to this if I can...given the hundreds of submissions. I am rating 4/5. Good job, loved the guitar themed. Bonus star for that :)

Oh, fun concept (I can see the Enter the Gungeon inspiration here too ;)) -- The difficulty is a bit high (I was only able to get to the second boss phase and getting booted back to the start felt a bit brutal), and it's a lot to keep track of for someone new to the concept, but mixing movement + dodging and a rhythm game together felt a bit like playing drums. Cool idea and the music is a bop :)
