In the latest post-funding update for Sui Generis the developers address the concerns over the released pre-alpha video.
More information.Running improvements and combat controls
Many people found the poor running motion in our latest video quite distracting so we made an immediate effort to improve it. There also seems to be quite a lot of confusion about how the combat works so we made a new, more detailed explanation of the controls as they are in their current state.
There is a lot of room for improvement in the animation system in general and inevitably it draws people's attention. While we do want to continue improving animation we're currently focusing on other aspects of the game.
You may notice that at times the characters seem off balance and recover somewhat unrealistically. While this is relatively easy to improve in a way that would look better in a video it would also take away control from the player by causing involuntary steps and shuffles. We're prioritising gameplay, better to have something that's fun to play and not just nice to watch! That said we can probably improve this but again we don't consider it a priority right now.
