I prefer using Easy Gif Animator Trial Edition.
And how to easily animate is to make a Big enough PNG filesize, usually around 64x64, with transparency background, and then have your sheet beside that in your own Paint Program(I prefer PSP), and then copy and paste each and every sprite of the sheet one by one, then after each time I pasted it correctly, save the file in the 64x64, then alt tab to EGA, insert image, and then use the newly resaved PNG file, then alt tab back and paste next sprite and repeat that.

makes animating sprite sheet alot quicker and easier to make it look correct.


Part 2.

I got to say I'm impressed how fluently you made these animation in such a small resolution.

The fires in the fourth tile set need to not look like a foreground to avoid confusing the viewer.
Rest is alittle bit too little to give any further critique nor comments. ^.-

Give a few examples of tilesets together to see how they make a bigger piece of a stage and to see how they connect?

These are hot, makes me wish people could make games that look this good.

They are too busy making games with HD/3D that we don't really care much about.

Can't wait till next magainze of Level to see what Junkboy made this time! ^^

An even easier to understand image


This should help you be able to make them more accurate to fix
And I like how it looks currently except from the northeast as others has pointed out has some blockiness.
