Weird, looks like something was writing teasers for me in my absence? Well, either way, good news:
Battle Fantasy v2.0: The Flashflame Update, is OUT! I highly recommend reading the changelogs before playing, enjoy!

Our mod has received a bug fix patch, a pretty important one because it'll be the last substantial one... for this version of the mod! More info in the image below:

Ello ello.
Aeronaut (the main dev of this mod, if you didn't know) now has a personal account here to share more informal updates and such, which you can follow @cbaeronaut.bsky.social.

As for the mod, we've slowed down because of school season picking up, but there are still fixes & such planned.

Some new friends have appeared in The Basement! Thunder Flower (definitely not a nod to Mario) zaps enemies into cold hard cash. And Interactive Buddy - well they were made to take hits. Don't worry about 'em.

Been a long while since we've posted a teaser hm? This is because we've been hard at work making sure we've been close to being feature complete before showing off more - in fact we are close to being 60 to 70% done. Stay cool! (But maybe not like the guys in this clip...)

Most of the items from our new update will be around the middle in terms of their power, in contrast to the items from our release. Don't let it bring you down though - the new items are bleeding with character... literally!

Now we reveal the next update's name: The Flashflame Update! As half of its name suggests, a number of items from a variety of Flash games will be present here. Can't catch the references? Don't fret, this simple trinket, Tunisian Diamond, will do that for you.

A small first look at our next big content update! It's getting a little toasty in here, isn't it?
