Really neat game! Simple story, effective delivery. Love how items affect time and have different uses. Great job here! For minor issues, I found the text block way too small and hard to read. You have a lot of space to play with. The text areas can be larger without compromising the look.
I'd also tweak the audio. Emilia is hard to hear. She's also quieter than Ganz when the person you're playing should be clearest. I'd bump it up to better match Ganz's level since his sounds the most balanced.
The music drowns the voices out when it swells too, so maybe pull it back more after it climbs. Beyond that, the game played great. The intro was a little choppy but that's no biggy. Keep up the good work and good luck on future games!
