SFW. Complete.

A Twine based human -> fox dungeon crawler with some puzzles (that were pretty bad when it first came out), detailed TF descriptions, and a lot of endings. Contains optional MC in some endings.

cough completely unbiased cough

Potentially NSFW in the future? (There were some NSFW in parts of the game's code prior to an update, but they were inaccessible through normal gameplay) Complete.

Human -> pig Twine game with 4 variations on one ending. Future updates may occur, potentially offering additional TF scenes.

NSFW. Incomplete, development status unknown.

Top down dungeon crawl featuring M -> M creatures via upside-down TF.

NSFW. Complete?  

A short and simple Twine-powered tale, with a few simple branches.  

(Human -> Pooltoy, anthro skunk, catgirl maid, semiferal doggirl, statue, genie)

NSFW. Complete.

A 2-3 minute breast expansion visual novel. Gameplay-wise, it doesn't get any simpler than this, but sometimes that's all you need, y'know?

Strawberry Jam 7 submission

NSFW. Complete.

A very short breast expansion themed GameBoy Color minigame. Mash B (the x key) as fast as possible to get larger sizes.

NSFW. Complete.

The sequel/reboot Reset Day is much better than this, but it's not as good of a fit for this list. If you hadn't already played Transubstantiation Synthesis, the TF elements in Reset Day would be fairly hard to spot. Dronification is the focus of both.

If you do play this one, definitely use Cheat Engine to speed it up. The walking speed is glacial.

NSFW. Complete.

Cowgirl or hucow (chosen at start) TF RPG.

SFW. Complete (jam version). Incomplete.

A simple arcade-style game where you turn people into sheep. The challenge level is just about right in my opinion, and there's some entertaining post-TF dialog for all the new sheeple.

Four legs good baaaaaa

TF Game Jam 2022 submission

SFW. Complete.

A simple high score chasing game focused on turning guys into statues (and then smashing them).

SFW. Complete. 

A short and cute puzzle game where you turn into different animals by mimicking their movement.

SFW. Complete.

Trapped in the baahahaha-dy of a sheep, what would you do? Essentially an interactive song detailing the aftermath of the main character's transformation into a sheep.

It could happen you ewe.

NSFW. Incomplete, still getting updates. (Review based on a previous update)

A farming visual novel with M -> F TG. While the ending still seems a ways off, there is already a surprising amount of content here.

Suggestive. Complete.

A branching visual novel focused on M -> F transformation. Memory/personality alteration is present in some branches.

NSFW. Complete. 

Examine the home of a witch to determine the whereabouts of a missing woman, or, y'know, get turned into an object instead (F -> pudding, pot, sock, "toy", sheep, cow).

NSFW. Complete.

Fully 3D, first-person, animated M -> F TG. The gameplay is nothing to write home about, but the animation is well done.

NSFW. Complete.

Explore a beach to reach 15 (and a half) endings focused on TFing into various types of mermaid, other ocean creatures, or even a simple bottle of sunscreen.

SFW. Complete.

Platformer featuring various F human -> animal TFs.

SFW. Complete.

Very short point and click with a branching narrative featuring super cute human -> dragon and human -> fairy TF.

(Mild) NSFW. Complete?

A short, mostly linear, RPGMaker adventure. There's enough variety in gameplay that nothing gets stale (block pushing, story segments, RPGMaker combat)

5 endings, 4 of which have been illustrated with Kisekae. (1. Bimbofication + identity death, 2. Kemonomimi-style dragon, 3. Inconclusive ending, 4. Succubus + wish fulfillment, 5. Slimegirl + breast expansion)

SFW. Complete.

Very cute and mildly horrifying inanimate transformation game with a Christmas theme. There's a bit more too it if you poke around at the "end."

NSFW. Complete, though further updates are possible.

A dronification clicker game with obvious similarities to Universal Paperclips. Important note: This game has a built-in autoclicker. Hover over a button and hold the enter key on your keyboard. The game is very slow without it.

NSFW. Complete.

A collection of semi-interactive hypnosis tracks. The final track in the paid version features a randomized TF sequence.

NSFW. Complete.

A team-based multiplayer game focused on a variety of M -> inanimate transformations.

NSFW. Complete.

A short bimbofication game. There's no ending, which might enhance the dreamlike nature of this game a bit.

NSFW? Complete. Unplayed.

A 3D first person horror game focused on human -> feral TF. (TF is 3rd person, and fully animated)

SFW-ish. Complete. (Played a previous update, before it was a paid game)

RPGMaker game focused on F -> cow, F -> werewolf, M -> clown, and vampire TF, with an additional vampire -> bat TF, and possibly one more from an update. 3 simple puzzles, and 3 or 4 endings. Very cute, but very short.

NSFW. Complete.

M -> lots of stuff, Twine-based CYOA.

Update 10/18/2022: There is now a female player character version: https://supertaster.itch.io/metamorphosis-at-the-magic-manor-female

The two versions are separate purchases, so be sure of which one you want before buying it!
