Wow, that's really encouraging! Did you test how much memory your game was using - for images in Debug Mode, and overall RAM in Task Manager?
Check out the animation loader addon, it may help with the development stage. As I understand, it will allow you to store all images on disk and load them into sprites on runtime. This will keep the project small. When you are ready to release the game, you can import all animations into sprites.
EDIT: Are you saying that the exported game size was 94MB? This is not right. It means that Construct has removed all duplicate images. Or was that the size of NW.EXE file only?
