Press the green flag to start. Select either 8x8 or 16x16 for what size you want. Click on the palette to change your colour. Click on a pixel to paint in your selected colour, and use the slider to change the colour of the top 3 colours in the palette. Enjoy!
This is a much better version of my "Make a Pixture 10x10" project. This version uses clones rather than 100 of the same sprite, and with more colours. It also allows two different sizes. Everything by me. I may add music soon, type in the comments what you think some good music to go with this would be. The (worse) 10x10 version (also by me): https://scratch.mit.edu/projects/108300154/ Interesting fact: There WAS going to be a 32x32 grid, but Scratch couldn't do enough clones.
