Gaster kinda ruined it.
I was going to give this a 4/5 but at least you put some extra effort to it by converting the crashing scene to Newground's video browser.
Other than that it's pretty good. Especially the first few parts of the transformation You can feel the veins shaping and bones cracking.
Reviews for "Flowey's transformation"
i really love how you put extra effort at 1:12 and 2:27 to make the animation different than from the youtube variant. and a wonderfull job with the animation overall.
Aside from having even more wonderful Undertale content to appreciate, this animation helps us better comprehend the SCALE of the battle Frisk/Chara has at hand. Flowey is effectively the GOD of the world, toying with it as he sees fit, and this plays into the Fourth Wall breakage that makes Undertale so fascinating.
And this isn't even Flowey's final form. :D
I defeat him yesterday. This motherfucker.
