Wow XD! What an interesting game ^^!
Let's start with the "not so good" part first. The game is really confusing at first, and the controls are honestly very bad. I'm okay with the mouse sensitivity (don't get me wrong, it's waaaaay too fast but it's the "WebGL curse", so I don't care), but not being able to move sideways is really frustrating ^^'. The music is cool, but I would have loved a bit of sounds here and there, just to give a bit of feedback.
Okay, now the "good" part.
HOLY FUCK what was that xD. The concept of somebody day-dreaming is really funny, and the "IRL replay" at the end is AWESOME. I'm surprised you managed to create a robust replay system that works that well in only one week, and seeing my character in the office bonking chairs is absolute cinema xD.
Great idea, cool execution despite the roughness, so overall great work =)!
