Hello!

Cool concept! I like the idea of learning music theory through gameplay. I can't say I learned much but that was interesting and I'm curious how you could teach other concepts of music theory this way.

Some feedback:

• The visuals are simple, maybe too much, but I like them. Especially the color palette.
• The game froze at some point, I don't know why. I was standing close to a closed door and pressed space, then for some reason I could not move anymore.
• I could not defeat the boss. I feel like there might be a bug too, because I was walking on the right notes but nothing happened. Actually, none of the notes was producing any sound, and the partition stayed there eternally. So I had no choice but to quit.
• The music is okay, though I feel it could be improved. Some parts sounded disonnant, which feels especially wrong for a game teaching music ^^
• The scenario is quite cliché but it's fun and it's a nice addition.
• I wish I could unroll the dialogues with the keyboard (just press ENTER) instead of using the mouse only for that. Moreover you have to click on a specific zone of the screen (the "continue" button while it would just be simpler to click anywhere).

That's all I have to say. Congrats on making a game, I'm curious to see where this game can go if you keep developping it :)
