which one do i download
If you want to blow through it, and just see the story go with RC1_1, it's got a few bugs that make it almost too easy. If, however, you want something closer to the game's intent (and based on feedback) - download the beta. If you want the one that was for sure 100% uploaded prior to the "No Travel Game Jam" end-date, then RC1.
- RC1: No doubt it was uploaded it time.
- RC1_1: I might have gotten it up in time, not too sure. Fixes a few minor bugs.
- Beta: A weekly build that is closer to the actual vision with added mechanics and features on top of bug fixes (though will sometimes get fresh new bugs).
