Well , needs a lot of work.

Well i found it ok , but the game looks boring at first sight. the backgrounds were plain and all. Adding a lot more features to the game would be great . It was an ok-ok game but i trust you in making a better one.

suggestion

as the previous person said make the apperance mor appealing. also im not sure if it was just me but it sounded like the quality of the notes were a little poor.

A working idea

its a start, but it needs a lot of work. You managed to make it work, so you know what you are doing, but the game doesn't look to attractive. Work on the appearance of the menus, add some animations, maybe a feature to change the pitch of each note, and maybe, if you can, add a feature to let people share their creations with each other. Then this game will score much better. You have some work to do but it can be done. Work on the art and people will like it much better. Good luck. :)

Needs alot of work...

I give you props for the concept, but the real problem is that is nigh impossible, a) to figure out how the darn thing works (but a little time with it and i got it, the ui is actually pretty intuitive after you get the hang of it - for this, i just suggest putting in a directions screen or a tutorial), and b) to figure out which sounds are which and where they are being placed - in this respect the ui is terrible, there are too many samples for to give the ui the minamalist look you are going for, the dynamics are pretty good, and there are alot of options, but there needs to be a way for people to remember what the heck they are trying to accomplish.

hmm...

It was a good concept but failed to deliver in the "tediousness" of the beat mapping... also not knowing which loop is which makes it a guessing game of "creativity" and not exactly easy to map it out correctly. Still points for trying and keep up the work.
