Thanks a lot for the animation tips, because I know almost nothing about animation, but I can't apply them =/
I didn't decide on making two frame animations, that came from the dev, and game movement is grid-based (and turn based for that matter). The game is a roguelike so that it is actually *animated at all* is quite out-of-genre.
I haven't seen these sprites in-game yet, but I've seen the hero sprite, which shares the same spritesheet layout, and looks believable.
