This game, written for the Neo Twiny Jam in 500 words or less, describes the experience of looping dreams, trying to wake up.
It's a simple concept but executed well. Everyone knows (well, at least people that don't have issues impacting their dreams) that feeling of thinking you've already waked up and then realizing it's not true.
The game branches a lot, at first appearing like a time cave structure, but it's slightly more complex than that, which I thought was cool.
