I'm not really sure what's going on with this game. I did notice the mouse weirdness (not sure why you're basically emulating your own mouse), but I seemed to be able to work around that by using fullscreen. I also noticed some of the game was cut off of the edges until I put the game in fullscreen, so maybe you have your project resolution wrong?
I couldn't seem to be able to do anything other then trigger that short scene with the clock button. I'm not sure if I'm just doing something wrong of if there's an issue with the game. I'd appreciate some sort of tutorial / explanation, either in-game or in the description of the game's Itch page.
