No problem at all, in aseprite i can open multiple files as an animation. i did that and export it to a spritesheets so i made one sprite sheet for each animation since they are not all the same size (make it easier for splitting in the engine). it' not so long after all. So far the worst was the idle loop since it's divided in 3-4 animations. but it wasn't so bad. i'll look into the tool you linked me tho. thanks for the reply. and no worries at all. stay at peace.
