Hey voidulim, thanks so much for your message and I'm really glad you're happy with the design!
Regarding KAEL-09 (Operation Neon Blade) and Belkar (Des Monarch), these are separately released characters, so they're not automatically included in the Founder Bundle and I don't have a way to add them to your existing purchase.
However, since you're a recent buyer, shoot me an email at the address on my profile and I'll gladly send you the most recent characters at no extra cost.
As for the action animations (pause, death, attack) for the Archer and Thief series, they're on the way, thanks for your patience!
Cheers, Sakpix
