Don't know if this is where you want it posted but here's a list of a few bugs I ran into while playing.
Sometimes when using the Medkit to reverse the transformation I end up in a glitched state where I'm constantly switching between normal and halfway transformed while moving.
While on the pig conveyer I sometimes get stuck in the wall at the end and can't enter into the pen and get a forced softlock when it punishes me for not obeying .`
The black blob snagged me through the wall before I grabbed the Level 1 Keycard, maybe an overzealous hitbox of a one time glitch since it only happened once.
This part is just a few nitpicks I had that may or may not be intentional due to the nature of the game.
The white goo puddles on the floor tended to blend in for me and be hard to see (This could just be my eyesight; but maybe a darker outline or changing the color of the floor might work)
Being able to aim better, maybe having it track the mouse instead of the way your facing since it was a pain to try and aim at the wolf by the heart key without getting caught or having it block the path with goo puddles.
I know only the first level keycard is in the game but maybe having a little icon in the corner or something that lets you know what level access you have since I didn't know what the card was the first time I grabbed it.
I don't think this is a current option but maybe turning on a setting that lets you alter the speed of the transformation.
Once you reach the end of the Demo and find the note that activates the teleport circles, maybe give an item or something that makes you immune to being transformed or captured so we have a chance to take a look at the WIP areas without being attacked on the way.
Overall this was an enjoyable experience and I am looking forward to the updates, especially after seeing the WIP content at the end. This is a type of game I'm surprised hasn't been made before now, or if it has I haven't seen it.
