Thanks so much for the feedback! Spacebar to end turn is a great idea. I'll add that ASAP.
I'm also pushing updates every 2-ish weeks so if you're interested in playing more we'll have a new version up in about a week and a half. The focus for next patch is to mitigate any output randomness (currently it's possible to get a match that you had no way of anticipating and that feels bad). I have what feels to me like a pretty elegant solution and I'm excited to see how people like it. :)
