It looks really good. Thanks for sharing. Maybe you could focus on the basic platformer animations: idle, walk (left or right, done!), jump and fall.
Also it would be really cool to learn from your .blend file. [Update: I found it on your itch-page.]
How did you render the images with a transparent background in blender?
Yes, I got carried away a little with the animation to-do list and got distracted by other projects. They're sorted by priority though, so I'll get to those first going down the list. The perspectives and directions isn't what adds most work. You may also be interested to see the repository with CI rendering.
How did you render the images with a transparent background in blender?
In Cycles that's under Render -> Film -> Transparent, with Blender Render it's over at Render -> Shading -> Alpha (Transparent). And make sure your Render -> Output has an alpha channel, which I believe it has by default.
Btw, note that the animations list contains four "walking" animations; Sneak, Walk, Jog and Sprint. The animation called Walk will be for use with slower movement than the (existing) Jog. Of course you can rename things as you like, if you're not using the other animations. But in most games you'd want your character to at least jog, despite calling it the walking animation.
