Use the arrow keys to dodge le bones (Yes, I've realized I say "le" a lot...). The HP loads a while - Why? If I don't it's like the Undertale Pong. It makes you lose 5 points or so. So now you can only lost 1 point slowly! How wonderful (I guess)! XD When the Gaster Blaster sound plays there's none :P I'll work on that! In my point of view, it's easier to rapidly hit the arrow key you are using. I know it's kinda raggedy (man. Lol thats a Doctor Who reference) but that's why it's best to do it. That is, if you wanna go too fast and hit the box. And yeah, the box makes your HP go down. And the bones in the box aren't supposed to move, BTW. They're also the challenge.
Megalovania Ochestral Remix: https://www.youtube.com/watch?v=tVuvTKMpDcM A story on making this: --- The last time I made a (unshared) Sans fight was 5 months ago or so. It was fully finished but didn't have most of the things in this version (thanks to my coding club helpers, I learned!). I accidentally thought I deleted the bones but until now I realized I might have forgot to scroll up but I think I only had a little bit of sprites but hey, this is just an improv. version I guess...
