I like the general idea - parents preventing you from sleeping is not a very common trope - but the implementation could use a lot of tweaking.
First of all, the house is way too big for the events unfolding in there. Most of the rooms are empty and unused. Almost all of such rooms are never even visited by the player. There's just no need for that. Moreover, the house looks really weird. Sometimes, you can see big holes between the walls. It would be easier to get rid of them if the location was not so big. Quality over quantity!
Secondly, the UI could use a lot of improvements. The default Unity font, buttons and filled images do not look good in this game. There are nice free UI packages on the Asset Store, so I recommend using them for quick UI design.
Also, the parents with their low poly style do not fit the environment at all. Imho, this doesn't give them eerie vibe or something like that. It just makes them look... redundant, I guess. And the fact that both mom and dad know only one phrase and will repeat it over and over each time they approach your bed doesn't help.
Finally, the ending left me with more questions than answers, to put it mildly. I mean... I know I'm a disgrace, right? Just tell me why the hell do you not want me to sleep!
I think, if you'll work on these issues, the game will become much more appealing!
Thanks for sharing the project and good luck with your next games
