Walk the words!

It is in my humble opinion that standard text is boring. Therefore I propose a new writing standard, walking words!

Walking words

Walking words are words which will respond to certain characters. For the purpose of this challenge the trigger characters are [u, d, r, l] from up down right left.

Whenever you encounter such a character when printing text, you will move the direction of the text.
For example, the text abcdef will result in:

abcd
 e
 f

Rules

Both uppercase UDRL and lowercase udrl should change the direction, but case should be preserved in the output
Input will only contain printable characters (0-9, A-Z, a-z, !@#%^&*() etc...), no newlines!
Whenever the text will collide, it will overwrite the old character at that position
Output should be presented to the user in any fashionable matter, but it should be a single output (no array of lines)
Trailing and leading newlines are allowed
Trailing spaces are allowed
Standard loopholes apply

Test cases

empty input => empty output or a newline
u =>

abc =>
abc
abcd =>

abcde =>

 e
abcdde =>

This is code-golf, shortest code in bytes wins!

Answer*

If this is an answer to a challenge…

…Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.
…Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one. Explanations of your answer make it more interesting to read and are very much encouraged.
…Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.

More generally…

…Please make sure to answer the question and provide sufficient detail.
…Avoid asking for help, clarification or responding to other answers (use comments instead).

How to Format

create code fences with backticks ` or tildes ~
```
like so
```
add language identifier to highlight code
```python
def function(foo):
print(foo)
```
put returns between paragraphs
for linebreak add 2 spaces at end
_italic_ or **bold**
indent code by 4 spaces
backtick escapes `like _so_`
quote by placing > at start of line
to make links (use https whenever possible)

<https://example.com>

[example](https://example.com)

<a href="https://example.com">example</a>
MathJax equations \$\sin^2 \theta\$

How to Tag

A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.

complete the sentence: my question is about...
use tags that describe things or concepts that are essential, not incidental to your question
favor using existing popular tags
read the descriptions that appear below the tag

If your question is primarily about a topic for which you can't find a tag:

combine multiple words into single-words with hyphens (e.g. code-golf), up to a maximum of 35 characters
creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
