MS Paint

Imagine all those fun times, lovingly painting the amazing scene of a cow with a huge lump in his head with a oddly sombrero shaped UFO flying above it (Don't Question It)  Now imagine that on the computer, but you can delete any mistakes quickly by doing Control + Z!  Now imagine instead of paint you were using huge messy colored paper cutouts.  This is MS Paint.  At a normal scale, pixels are fairly small but still slightly visible, and at a large scale the biggest brush IS TINY!  Wait a minute... You can't change the scale!  WHAT IS THIS.  The painting isn't very intuitive.  For the love of chocolate, you make one mistake and you're done for.  Try to make a circle but make a mistake?  You can't erase the bad area because it would erase the background too, so you have to hit Ctrl Z and start all over again.  So then there's one strategy: Taking "Draw Breaks" In small segments.  So if you mess up one you don't have to restart.  The problem with this is there is a difference between lines and could look uneven.  Example:

Circled in red are bad transitions (Left to Right)  This one is noticeably thinner showing it's one of these points.  This would be because the new point starts is farther away from the last ones end.  The next one is because of bonus pixels at the top.  This might be because the two were overlayed slightly off.  This is the same with the final one, except the result was it's noticeably fatter.  The one circled in green is the winner, not thin nor fat or extra pixels.

But this isn't the worst part of Paint.  Oh no.  The selection tool:  Because of the nature of ONLY HAVING ONE LAYER paint's selection tool sucks.  you select a box?  IT TAKES THAT BOX AND REVEALS THE BASE COLOR BENEATH IT!  This ends up leaving a gaping hole in your picture, often ruining it if you just go with it.  And even if you somehow manage to perfect free-form selection, it would still leave a cutout of what was there.  This is one of the most annoying things about paint, but not the worst.  Really, just having a background setting would be good.  

Let's talk about brushes.  These splatter pixels representing paint/ink on the screen (I'm starting to sound like I'm doing a Splatoon weapon review)  but that's it.  They don't show different movement styles of brushes, they just simulate spread and seethroughness.  It doesn't really show actual painting whatsoever.  But the worst part about MS Paint:

Lets say you have a shape.  It's the lightning bolt, the last of the 23 shapes (Microsoft WORD has 160 Shapes!  And that's WORD!  Paint should seriously step up their game)  Onwards, you shape it perfectly like you want it then disaster strikes:  When trying to change a color you accidentally deselect it.  You can't click on it and the box comes up again, it's plastered into paint right there.  It sucks.  It sucks so much that it keeps me from mentioning the bad user interface, which is mainly caused for me by not being able to have that green thing to rotate and not being able to flip the shapes by dragging one scale side over the other, because honestly paint.  Who want's final edits to be the first other than bloggers?  That's what I thought.  Middle Schoolers.
