Some more issues:
1) If a spell takes as many magic points as you have left, it doesn't do anything. (I had 50 and tried to do Mind Reading, and nothing happened. I then recharged my magic, and it worked.)
2) Doling out treats doesn't decrement the count in the inventory and doesn't remove the inventory item when depleted. Internally, it knows how many treats you have. If you do run out and then try to give one, it gives an error about no menu options.
3) If you try a sleepover with a pony without sufficient affection, there is a brief message that you can't read and then the screen clears and you're back out in the hall. I assume you got booted out, but it would be nice to be able to see the message.
4) Given the general present tense-ness of the game, something like this:
"Oh hello there..." Kimono paused as she clearly forgot your name, "whatcha want to talk about?" she asked happily.
should be:
"Oh hello there..." Kimono pauses as she clearly forgot your name, "whatcha want to talk about?" she asks happily.
- or -
"Oh hello there..." Kimono pauses as she has clearly forgotten your name. "Whatcha want to talk about?" she asks happily.
I like the fact that the ponies are in different places at different times of day.
