Hey, this was a bit broken from the technical standpoint and the first few choices were completely pointless but overall, not a bad story! I very much liked the framework and how you portrayed the protagonist's emotions when confronted with someone from her past. Also, the voice acting was really well-done.
You probably don't care about my opinion, but you could expand this into a really nice commercial VN. As vanilla as the story is, it hits all the right notes for a yuri fluff game. You'd only need to expand it a bit and elaborate on Tomoyo's character and her past with the protagonist...
Anyway, I'm just rambling at this point... Still, nicely done!
