I've updated (and uploaded the changes to) the templates now. The ILF format has been changed a little, but if someone already has made an ILF file, I can tell, that I've made a converter to fix it for you (Tools -> ILF Converter in the template tool).
I have also made a minor change in the spell format, but you need to do it manually; if you have made any spell files (NSF) yet, open it in e.g. Notepad, and insert the integer 20, followed by a space, in the beginning of the file. It's only necessary for any spell files made -before- I posted this.

EDIT: Same download link as before.

Thanks
Yeah, I've also got a few ideas for improvements; e.g. Save/Load, as you mentioned, enemy health panel, and a trading script. But thanks for the ideas

Well, my time is running out, and I have to go now... Cya later
