Good idea and decent execution, but it kind of dies on the main character's design, unique as it may be (I can honestly say I've never seen a character design that was just a line with eyes), it kind of blends in a little too well with any background that's not a perfectly solid color.
The animation was kind of choppy too and the abrupt cuts are pretty disorienting, specifically when he fell down the stairs or when he was hit with the fire extinguisher, this has away of taking away the impact and killing the gag.
Overall, I'm happy with the fact that you said you're going to remake it because I see potential for a good short here, and I will be following you for when that remake is complete.
