A solid base for an interesting game. The premise definitely appeals to kinks far beyond the usual. The visuals are pretty and really well made, and the character customization is a wonderful touch for this type of experience. Chasing other critters around was an interesting challenge due to the bushes slowing you and others down, they can be a run ender or a super useful asset depending on how well you can take advantage of them.
I wasn't sure if there was an audio issue on my end or if it was set up to be a very low volume or if the game really is 100% silent, but I haven't had any sound issues with other entires so I am to assume the latter (please do correct me if I'm wrong!).
As for balancing, it's a bit bothersome how NPCs can go off screen since you can't, and NPCs in general tend to have a strong bias towards capturing the player if you end up in a 3+ tackling situation. You can also easily spend ages getting used if you happen to tackle something just within the edge of town. I do wish there was some indication as to the town's location since right now the only way to tell is by getting picked up and seeing generally which direction you are taken in, but maybe that's part of the design.
Otherwise, this is a great proof of concept! I'd love to see a game with this premise getting some more breathing room to develop into a larger project, specially with such well polished art and following through with the more taboo kinks out there.
