Sorry for the late reply.
TLDR : Some of it is in the next version, some of it isn't.
1. The next version uses the idle animation in the gif. It's far more natural than the current idle stance.
2. The gif has walk and idle versions of attacks. This wasn't in the plan, though its less labor intensive than I first believed.
3. The gif has attacks which sync forward and back swings up with the walk cycle. It's a neat trick but hard to implement in game and would mostly go unnoticed by players.
4. The fiery sword effect is already implemented in the next version.
Below is a link is for the private preview for the new version. If / when it releases it also covers the price. The link only works once, and isn't tied to a specific account. Nobody will steal it though, because everyone who likes my work is honest and respectful.

Seriously though, I appreciate when anyone expresses interest in my work. Thanks.
