Extremely interesting and time consuming (in a good way)

I’m very glad that you made this into its own game because it was a pain to have to pay 50 diamonds for a every new song I wanted to create. I also love that you added how one monster could play the melody and harmony instead of using like 5 other monsters to make one chord. But a couple of things that would make this game be able to go even further is if it had a bass clef. It would help sooo much when you want to make it sound like it all ties together. Another thing that would definitely help is if you had a larger staff. In a couple of the songs that I wish to do I can’t because some of the notes have to be dropped due to only having 3 notes above scale. It’d be nice to 6 or 7 or even more if possible. Finally I’d really think it’d help a lot if you made it able to have key changes in the middle of a song. It would be sooo much easier to just switch my c key to B flat major in the middle of the song instead of trying to figure out how to transpose all of the notes. Yes I do know that this game might be targeted more toward children but I think it would add sooo much more creativity and room to explore with the things I suggested. Again I love this game and it would still be a great game but if you want it to be awesome, then I think you should consider my recommendations.

I love this game!

As soon as I found out that this was an app, I immediately downloaded it. As soon as I started playing, I couldn’t stop. This game deserves more love and people playing this wonderful app. I really like that you included dipsters, because I don’t need to replace it with maw :D. I also love the rares update. It’s really useful that you added the basses and extra beats and rare instrumental monsters. I really am excited to hear when the new update is coming, or what the update will be. Here are some things I would like the be added in. 1) Smaller Monsters or a Bigger Island (To fit in more monsters). 2) More Monsters. 3) The ability to move the length arrow diagonal. 4) More notes to fit in. 5) New Monsters only in this app (Maybe). I like the game how it is, and I think nothing is wrong or glitches out or needs to be fixed. I’m really glad that this is a thing and I can actually play it offline! Anyways, wish you good luck on animating and voice acting and coding and updating the game! Happy Monstering!

Can’t stop playing 💖

I absolutely love this game. I always wanted to compose songs in msm, but in the regular Composer Island, it’s a pain having to buy the islands if you wanted multiple songs. In this app, you can make as many songs as you want, and you can do it all for free! I really like how the rare monsters have different sounds, and I absolutely love the fact that you can have the same monster sing up to five notes at the same time. Also the game doesn’t need WiFi, so I can play it anytime, anywhere. One feature I would love to see however: in msm and msmdof, you can visit other players’ islands. I’d love it if in Msm Composer, there was a feature like that too. (You could still compose songs offline, but if you are online you can see other songs people have made.) I think not just me, but a lot of other players would love that. But overall, this is one of my favorite apps, and definitely the best composer I have used!
