Fun fact, I happen to be an artist that worked on 2D animation along with other projects. Video clips, trailers, game concept arts, and pixel art etc. Just so you know, the work needed (scetching, drawing, coloring) for each frame as well as the background behind it (that I put as an extra just because I want to prove you wrong at the worst case scenario that there's simply TOO MUCH work) is about 1-2 weeks at the VERY max, to finish (an animation of their ability, which is extremely simplistic, very few frames and stationary poses that don't change). I used to work solo or with a team of 4-5 people. I give them 2-3 days for sound, and the rest for the programming. 1 month would be a lot more than enough to produce this quality of finished product.
Plus, I used to be a patron of them as well, not top tier such as others but I gave them a little something. I stopped the moment I saw this ridiculous postponing. You can still be their patron if you wish, or believe what you will about their work and doings. But please don't try to convince others that they are not scamming people. It is pretty straightforward at this point.
