It's an extremely disappointing and limited tool.
It exports the sprite only in sprite-sheet and every exported GIF receives a size 4x larger than the original. and no, you cannot choose which size to export.

Sometimes the program also crashes in the middle of the project and you lose progress. It's not like it takes a long time to develop the animation in the software, but it's terrible having to do it all over again.

There is one small thing that always irritates me about this program is that it has some bars for you to drag and select the animation movement value, but if you move this bar from the center, you cannot leave it in the center again just by dragging, you need to click on the bar and select the average value manually every time.

And finally, it's horrible to mess with the tool's settings, because it's either bugged, or limited, or has a terrible setup (like selecting the sprite size when importing the art).

The idea of ​​the tool is very good, but the software itself was very poorly designed. it is not optimized, it gives glitches that can compromise the project, and in terms of capacity it is extremely limited.
