Once the code works you can either decide to squash everything in the minimum number of lines possible or to keep it fully indented: it's just a matter of personal taste. I prefer reading 1k line of nicely-indented code than 200 of obscure 400-line long code that does the exact same thing. Remember that as soon as the "development process" is finished, you'll need to read the code more often than writing a brand new large section (squash bugs, improve performances, add features, etc). Nice indenting (and possibly lots of comments) makes code more "typo" resilient and helps also other people looking at your code to understand what it does.
