arrow keys to move, dodge attacks tested and no hittable made for @Dragon_113's contest Undertale: Dark Night by me DustNight (Dark Night!Sans +Murder!Sans) press green flag twice to avoid hp issues
everything made by me except music (Undertale Gameboy'd: Broken Emotions) by Louis on YouTube, sans sprite (which i edited) by Agony24 on DeviantArt, gb sprites from Undertale Last Breath by ZerJox, game over theme (It's Raining Somewhere Else (Cover)) by Unspiral Da Braindead Dude!! on Youtube, and obviously UnderTale, by Toby Fox, Temmie Chang, and others. im kinda lazy so not many attacks no engine used (because i didn't realize we could use them until I finished) so its pretty bad
