I love it! But it can use more features

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. I also think there should be more monsters. The monsters currently in the app are all good, but considering the price, I think that monsters from dof should also be added. This game has gone on for awhile with no updates, but I think it needs more. I also think people might need more measures to use in the songs, in case they run out of space. I’ve had this issue a few times, but I don’t think more measures are absolutely necessary because I get that adding more may take up too much data and possibly cause lag; they’d just be nice

Best composer game ever, but a bit from the original MSM missing

Hey, Monster Handlers! I just wanted to say that your MSM: Composer is totally awesome. But, there is some stuff from the original missing. What am I talking about? The Wubboxes. Those are my favorite monsters (other than the ones at Starhenge in Dawn of Fire. Those are true epics and totally worth it if you get them). I have seen them on the original Composer Island. Most of the Seasonals and all the Epics are missing, too. I also think it would be cool to add the Dof monsters (including the celestials, if you can), Wublins, Magicals, Eth. Workshop monsters and Celestials. If you are thinking, “We can’t add some of you’re ideas because they have too many sound effects/appearances (Appearances as in Epic Wubbox, Shugabush Oaktopus and Shugabush Furcorn),” I think I might know what might help. Some kind of skin/sound effect changer that lets you pick which sound effect/skin that the Monster(s) make/have. It would also be cool to add the sound effect changer to other monsters that have one or more extra sounds that aren’t when you make the note longer. Also, could you add dynamics and different types of notes, like half notes, eighth notes, etc. Could you also add slurs on notes? That could make the notes more interesting and fun. Welp, those are all of my ideas about what you could add to the My Singing Monsters: Composer. Thanks for reading this, and may you have an amazing day!

Amazing but missing a lot

I love this app! In a lot of ways it is better than the composer islands on the regular My Singing Monsters app. However, there are a lot of features missing I wish were included. Some things from the original composer island and some things that just should be included. I wish the monsters could be moved around the island because the 3D sound is often ruined by the long notes version of a monster and the single notes version of a monster being on opposite sides of the island. If we could move the monsters, this issue would be resolved. I also wish you could have multiple of a single monster. Sometimes I want the same monster to have different volumes and there are a lot of tricks with this you can utilize on the regular composer islands. I also find myself limited by the monsters' ranges. A high B# (C) doesn't often cut it and sometimes I want to go lower than a low Bb. If we could select different octaves, even just one more in each direction, it would increase the capabilities exponentially. Another long shot but still fun idea would be to add the fire monsters. I know this would take a lot of work but there are a lot of new sounds from them I wish I could use. Overall I love using this app!!
