Congrats on achieving the 1.0 milestone after all this time. It is wonderful news. Someone should update your moddb/indiedb pages to spread the word and you could also request animators to add some more life to the karts and characters. I recently saw a talented animator release a free model pack for SonicRoboBlast2 Kart (SRB2 Kart). Here is the trailer he made for his release.
