Despite the game still being capable of changing Zeno's sprite and sprites of Zeno with a larger belly being seen from the slime eggs, the weight gain system seemingly does not use this despite also appearing to in the prologue section. If there is an actual system that allows you to vore enemies in this game, then it sorely requires a tutorial. Currently, the only enemies I can consistently vore and gain weight from are slimes, which also reduce stamina when doing so.
Another issue I have is that certain enemies are annoying to view the grapple for.
The mimic seems based on LP, which can take a while to fill, and if Zeno dies at all during the fight, the mimic won't be there to fight again.
Forest Bush 2 seems adverse to using its grapple, despite the game saying its interested. I stalled the fight for dozens of turns waiting for it to grapple and it never did.
Seemingly neither the Faerie or the Rapaw seem to gain any sort of attraction to Zeno, and I'm not sure if that is simply how they currently behave or if they are not working.
Even when or if one does get these grapples, it is a one time thing and then it is impossible to view them as they are not included in the gallery.
I'm not sure if anyone else is having this issue, but the gallery seems to keep resetting itself due to an unknown cause, so any scenes I do manage to obtain are disappearing.
