First post here in a long while, wasn't what I was originally coming here for (that'll become apparent soon enough .) but I thought I'd share what I found the other day. I was having a look through on GB64 to see if anything new Boulder Dash wise turned up, but instead of taking a look through the long way like I usually do I actually looked what was added in the update. Seems there were a few new ones that I think look like important ones anyway. I'll link them.
Sorry if this is already known but I thought to share it here anyway, there are many others over there that I did not know of before but these ones I feel are sort of main ones. In case it could be added to the cave maps section or be converted to GDash or whatever.
Testing and fixing up some caves for some releases, coming soon for real this time!
