This was such a fun short experience! There is charm in just about everything: the dialogue options, the random inconveniences, the Duolingo LOL. I don't have any complaints; it was just really fun. It was interesting seeing all of the different dialogue options for each ending.
The music you chose really adds to the quirky nature of what's happening. It's definitely a scramble to make sure you don't game over, and the music lends itself to being both cheery and intense!
There were no bugs I experienced; everything was polished from my perspective.
The double meaning of unstable is so good! I didn't even pick up on it until I read your description. It fits the theme perfectly!
This entry sets out to do exactly what it needs to. Fantastic stuff! :)
