Investigation Comparison: Flipbook.

 I gave Flipbook a fifth-teen out of twenty because I rated it in four different categories. Simplicity, Characters, Color, and Background. Simplicity is how easy it is to understand what to do. Characters are the people used in the tool. Color is the variety of colors to chose from. And background is the well, background options in the tool.
 I gave simplicity a five because I didn't need to read any instructions to know what to do and how. It is quite obvious for me to figure out what to do but my opinions may differ in others prospective because I've used some tools that are similar. Therefore it might give me an advantage because I have experience.
 I gave Characters a four because you can have any character you want but you cannot pick it, you have to draw it yourself. It gives you limitless decisions though so that is great. But I did not give it a five because some people do not wish to have to draw the figure itself, instead pick a character that is already made for them.
 I gave color a three because you can have a choice between a variety of colors but there are only twenty-four to chose from. I wish there was an option to chose any color you want but the twenty-four colors will do.
I gave background a three because you can draw any background you want, the possibilities are limitless. But some people may have a difficulty drawing a background for each frame.
 I gave this tool a fifth-teen because although you have as much freedom as you want you have to do everything from scratch. There is nothing else besides colors, sizes, and your imagination. That's not too bad, right? Unless you feel like doing easy work.
