Pixelo Editor ( Pixel Art Maker Just for Fun )

Hello there..!! So, one fine day I thought of learning how to make pixel art but then got distracted and thought I would make a Pixel Art Editor first and then make pixel art using that. Here is that. I made it in 3-4 days and just for some fun. So, it does not have all the features of any advanced Pixel Art Editor. But it has all the basic ones that make a Pixel Art Editor functional enough to create and export an art piece. 

If you feel there are certain improvements that can be made or new features that can be added then do let me know in the comments.

Controls - 

1.  Left-mouse click and move to draw on the canvas.
2.  Right-mouse click and move to erase pixels.
3.  On the left, you can use settings to change the brush color, opacity, pixel size, and background color of the canvas.

It was a very interesting project that I worked on during my free time and would love to add new features to it if necessary.  Thank you very much if you used it. Let me know in the comments what you think of it.
