Nice concept. Needs a bit of polish.
It is a nice concept and I'd like to see a few more episodes. Overall, I enjoyed it, though the story dragged on a bit too much. Almost to a Monty Python "get on with it" level. The sub-plots, such as the romance segment had nothing to do with the main plot and were a distraction. This wouldn't be bad if it was the main reason for the guy ignoring his tax problems.
The animation would have been more entertaining if the length of each day was shortened to a few seconds, with each day being its own gag or strung together for a gag. The days in the park where the guy played fetch with various animals, is an example of this done well.
The ending would have felt less anti-climatic if the guy was still worry-free after the repo, pulled some deus-ex-machina to keep his home, or more emphasis was placed on him realizing his stupidity.
Curious where you go with this. Will you keep the same main character and flesh him out over time, or have a character-an-episode? Will you place more emphasis on drama and a hard Aesop, or go for a more comedic approach? Will your animation quality improve or will you go for a stylistic suck? Best of luck.
