I'm assuming you're on Windows. Yes, currently, the Windows build is 32-bit. We plan on including 64-bit builds for future versions.
As for bots, there are computer characters in the game. You can start arena matches against computer characters and find enemies in the cave as well.
We are on Steam Greenlight and have already been Greenlit. We are working towards a more polished version before releasing on there. Nevertheless, we appreciate your support!
Hope that answers your question.
