Good game, but I've run into a problem where my data gets erased every so often, so I lose all the songs I've made Edit: I've run into this problem once again after a while of it not happening, I thought they had fixed it but it turns out it hasn't been patched. I'm honestly disappointed that this bug is still in the game even about a year later.

I mean, what else do you expect? It's cool for testing out monsters and is fun, but it feels extremely outdated. There haven't been any updates to the game for years, and it's not fun with nothing new. However, there are positives! This game widens the features you get with composer island, making it so you can overlap monster tunes, use a few rare monsters, and seasonal and ethereal monsters as well.

Pre 2.0: This is the second time all of my data on this app has mysteriously vanished. I now know how to save a song as a .msm file and open it again in the app, but this is not clearly stated. The reoccuring data loss needs to be fixed and the saving process needs to be simplified by a lot. Post 2.0 edit: I am pleased by the new features added, but my previous review still stands. Also, the spunge's long notes are almost an entire half-step out of tune above high E; it sounds really bad.
