FINAL BOSS HAS 1 BILLION HP. YIAZMAT IS JEALOUS.
Incredible from start to finish. The battle system is creative and strategic, the story is gripping and interesting, the characters are enjoyable, the music is great, and I'll never get over the voice-over battle transition theme.
I find it interesting that you used synaesthesia to drive the plot. Very clever. I noticed it early on, since someone close to me has it. It reminded me a lot of her. Because of that, I had a more personal connection than most would. I probably would have completed the game whether it was good or not just based on that. Also, I saw in the credits that "Karen Lee" was seperate from the rest, so I'm guessing the brother-sister relationship was inspired by real life, which is touching.
I noticed the game is very difficult. The battle system requires skill and strategy, and unlike most RPGs, you have to actually pay attention. No more fire-and-forget attack commands. Also, every character has a purpose, which you can decide to an extent. Although, their stats are similar enough to let you improvise in a pinch. I thought Chadd was useless until I learned his special skill actually healed HP, not status effects (which there is only one of). I didn't learn this until halfway through the final boss. Some in-battle skill and item descriptions would have helped, though it was easy enough to grasp (Food = HP, Candy = IP). Also, you had a lot of empty slots, which gave the impression they would be filled by endgame, but they weren't. Just a tidy-up issue, everyone has one.
While playing this game, I could sense the devotion in it, I can tell you put your heart in it. An admirable trait, and it will serve you well if you pursue a career in this. It's been a long time since I've seen that in a game.
