Played the new game and i say it has potential. I did notice a few things though (I know it's in Alpha phase at this point but better safe than sorry, right?)
1. In first person view, if you look all the way down, you clip through your own body.
2. I assume the second keycard not having a spawn is intentional, like the end of a demo, but I'll still put it here just in case.
3. I would definitely add a roaming mode for the SCP's, so they don't just stand around after you walk a certain distance from them.
4. Certain camera angles will get blocked by walls depending on where you are caught, such as nearby corners.
Other than that, i think You have a good base idea going on for the future. I also hope you add the ability to speed up through Sex scenes via clicking or pressing spacebar or something.
