There will be more, albeit the next project will be anthro. A Palmon Trainer will follow in any case in the future still. I imagine in Palmon Trainer one could have an optional scene to fuck Biyomon. But like I said, that is for the future. ^^
Palmon Trainer was actually the first game in development, but was then postponed as it was too big in scale. I have a very early prototype of it that doesn't have much to it. Simply Prologue. Something I will come back to in the future like I said, but Gomamon Trainer was simply better for a first project in the end. ^^
