• Does not import .gifs.
• Only imports .png files.
• 128x128 size limitation.
• Size size limitation prevents importing a png strip.
• Thus it cannot be used on png strips to create animated imagery.
• That means importing EACH and EVERY frame and then exporting EACH and EVERY frame in .png format and then cobbling it in another software to make anything animated.
• Does not export .gifs.
• Pointless for any serious game developer.

Regardless of end-user "license" issues of .gifs, the ability to handle them should be provided for ease of use. (Let the users manage their own license usage.)

Please permit importing of animated .gifs (and/or png strips) - and remove size restrictions. Else this software is for "fun" usage only and not for any serious game development.
