I think I did it right? Grab the key, avoid the faces, unlock the main door in the corridor and leave. The game runs smoothly and nicely, the vibe is creepy as heck too. It is a bit too simple for sure, but considering this is your first game, this is actually quite nicely done!
Other things I like:
- The rooms felt different from each other
- The face sound is really haunting
Suggestions:
- Some ambient sound would be great
- Consider some in-game instructions to tell the player what to do?
- Seems like the collider for the faces is huge, which led to a lot of unintended deaths. Usually it's best to cheat a bit for the player and make the enemy look larger than they really are. Make the game more fun that way
- Some cutscenes/animations that play after the player is caught by the enemies would be nice. Act as a way to tell the player "you've died"
