- It's got almost everything that I wanted in Paint Tool SAI. The only downside... no blur tool. I am really looking for a painting software with a blur tool. So... 4.5/5 stars
- Very advanced program that is absolutely free, only downside is that it's not as lightweight as SAI
- Too glitchy and too hard to use. It will zoom in and out randomly making it hard to draw.
