Update - here's some of what I've been working on.
Magic bolt
Ria's basic distance attack. Doesn't use much stamina, so it's useful for a quick shot to stop an enemy. Stronger enemies will need to be hit harder to knock them out of their attacks.
Ria's explosion spell

3D collisions
This gif shows how the units collide in 3D despite being a 2D game. They technically collided in 3D in the explosion gif too, but it was pretty inaccurate and I came up with a much improved method - enough so that I should probably redo the gif.
Other new features this update: There's new arrows while paused showing what the object's movement is, I used some free textures to improve the graphics, there's text at the mouse location showing what a click will do and I shrunk the HP/SP bars because they were blocking the view of the units entirely when they were bunched together. One downside of improving the graphics though is that gifs of the game are way larger. Not that it matters much for those on broadband, but those on mobile can get slammed by them, which is a big part of the reason why I'm keeping the frame rates as low as possible while still conveying the action properly. It's frustrating that there's still no universally accepted successor to the gif. :/
There's been a lot of other progress too, new abilities, items and enemies. It's still a ways off from being ready for people to play, but it's getting relatively close to being ready for me to make a video of a battle which will make it much clearer how the game mechanics work (if you ignore the lack of a level and other such missing content).
