This is absolutely brilliant. Today I finished the first chapter and I had the same feeling of post game depression i had after playing and finishing my favourite AAA games...
I really hope you will continue developing it, I hope it gets recognition (SPG, I'm looking at you) because you deserve it, Yobo. I feel really bad for not being able to support you yet, because I am in a situation where every penny counts but I will join your supporters as soon as I sort things out.
P.S. I saw you mentioning that you have plans for M/M, F/M and group scenes... My question is... is there any hope for us - futa enthusiasts? :D
