Thank you! Yes I had seen that in fact it did help bring from huge sizes down to a... more manageable (?) 980MB ish game. I just submitted it to itch.io as a "downloadable" rather than an HTML game, which will probably discourage many - if not all - from playing it, but at least I'm within the deadline and I will try in the next few days to work with itch.io support and publish it as a brower game even if it's > 1GB.
