Most gameplay stuff is NOT implemented. At present, our main concern is simply whether it runs correctly or not (or not at all). So crashes, performance, graphic corruption, etc., those are the things we're looking for.
Unless you encounter some gameplay issues that are very obviously implemented but broken (one example so far would be autocombat initiating only for the first unit in a stack, then you can go right past the rest), don't worry too much over them.
