I'm gonna head straight to the point:
There is some good news and some bad news.
The bad news is: due to some drama with me and someone, I had decided to remove the overworld sprites completely and decided to make a new menu because of it.
Please don't bug me what happen, I don't want to mention it.
ACT 1
I haven't really worked on it due to me having to just plot the story and how everything goes.
ACT 2
Okay now this is the good part!
Here are some screenshots of the battle!

( Also just to confirm: this battle is not finished )
Wait, but sans isn't damaged in ACT 2! Is something different about it too?!
So the story is:
Sans dies and Gaster sorta.. Takes your soul and breaks it.
Then since you respawn, you have to re-do the fight all over. But since Gaster basically remembers everything (and plot),
Gaster tells sans about it and sans is ready to fight again.
That.. actually sounds good!
Thanks!
I was being sarcastic.
:(
Anyway that's all!
Wait what. WHAT ABOUT ACT 3?! OR 2?!!!
I'm still thinking on a story on that.
And for ACT 3.. Uhh.. I guess I'll show a little sneak peak :)

Anyway that's all, see you guys later!
