Yes, its our first time using the engine, so we didn't knew about issues we would encounter. Sorry about that - we will try to check and solve issues postjam.
Combat is not build on reaction time, though - everything is turn-based. Your turn comes before enemy. You can look around (turning doesn't end your turn, moving, attacking and skiping the turn does) to check sittuation freely. Telegraph on the floor shows danger zones that will cause damage next turn, so you can move to the safe position without taking any damage.
