The video got me to download and look at the readme, but in general, it's not the best practice to tell people they have to download your program before you'll tell them what it does. This looks incredibly promising, even if it seems pretty incomplete right now. Main stuff that I'd like to see added or changed:

• The handling of the actual memory reading/writing could be improved, particularly since the addresses differ between JJ2 versions. I would much rather that health, xpos, etc., were constantly named variables, or keys in an associative array, than look up every time what their addresses might or might not be.
• No for, while, or else? Sad panda. Heck, more datatypes, even.
• The list of addresses you link to seems quite limited. In terms of save files, it seems to cover only the second block, but not the dictionary or event map or even triggers, which would seem vital to any detailed scripting work. Are these impenetrable to the current tools?
