It's because it's not "real" animations, I don't create an animation with the DAZ tool, but just make a "fake" one using multiple background images repeating in a sequence, but once the sequence is done, it stops. ^^
But I'll try getting my hands into doing some real animations next game, it's a bit too late to implement them towards the end of the game (though doing a little animation during the endings could be an idea, like a reward for all the hard work getting there...
).
And as we're on the subject of animations, why didn't I try myself to it before? Well simply because I always hated them in all the games I tried before making my own, I always found bothersome the way they were implemented, a forced video that pulled you out of the flow of the game (technically I mean, not story wise), but now I'm curious to try myself with it and see if they can be put in the game another way.
