Is it possible that I was rejected? Should I reapply? I am completely in the dark about what is going and what to expect,

Honestly I don't know what is going on in GameSparks but seems like they are either busy with something they won't tell us and literally have no time to come check forums/deal with requests (such as indie program) or they are downsizing which would be odd given the acquisition, unless Amazon decided it was time to go (as I know amazon is working on some other platforms that compete in some levels with game sparks). So I dont know about your request but, be aware that these days things are pretty slow apparently, which is a bit worrying.
