spider

What kind of character is this?
Spider is an animatronic spider. He has a rather memorable and slightly creepy design.

What are his mechanics in the game?
His behavior is designed to keep the player on edge:

While you're looking at the camera, little spider drones start crawling under your desk.
Your task: as soon as you spot a spider, tilt the camera downwards and click on it to crush it. If you don't do it in time, the spider will cling to the screen and block your view, making it impossible to click on it.
If you miss too many spiders, Spider himself will materialize under the table. After that, you only have a short time before he "completes the experiment" and the game ends.
A couple more details
In the first demo, Spider had no voice acting at all, but in the second demo, they added it.
The character has a few lines, such as, "It's about time we had a little pest control" or "You look like you could use some adjustments."
