Just a little too early to review, IMO.
Still gonna review anyway. (V0.2)

It's a basic VN so far, dangerously close to a "kinetic novel" or whatever they're called. The game doesn't really advertise what KIND of game it is outside of the VN tag, but that's what it is, in case you're wondering.

No branching to the story at all yet other than some really minor tweaks like choosing to grope Frenni or not, so you can pretty much just bumrush the whole thing in like 5 minutes if you're a speedreader.
One weird quirk is that the dev turned the chicken into a guy, which doesn't sound right to me as an outsider to the FNaF franchise's knockoffs and homages, I'm pretty sure the character's supposed to be female.
A downside of them making that one a dude is that you're forced into a mandatory scene of him stuffing himself, so here's your warning about dude belly.

From a game quality perspective and the assets in it, the whole game is obviously loaded with the usual random assets probably pulled from VRChat or other fangames or whatever, since most of these kinds of games just recycle off each other; the issue here is that most of the assets are regular Freddy's assets, so the walls have regular FNaF posters and such, and the Frenni crew don't seem to be built for actual same-size vore so the dev just slapped an orb onto the model and made it roughly the right color to match, which doesn't look super great, though the models include a LITTLE belly good for cumflation or other small changes.

Anyway, I should probably rate this two stars, but I'll round up since the game's so new and I don't have any "major" issues.
Would I recommend anyone play this yet? No. Probably worth following if you like bellies, soft vore, and VNs though.
