It really feels like a complete game and I think that in itself is amazing. I got to the good ending but I was a little heartbroken I didn't manage to convince Aira to trust me without the hint (even though she said she trusted me and that I could too! I got backstabbed!).
The Timeshift mechanic makes me feel like there's a lot of potential to the idea - there could be more stuff that the player can do to affect the outcomes. Overall it's fun and engaging. Nice use of TTS too. Awesome.
