and he's also pretty mediocre at art, temmie is good enough but that's still just 1 actual decent artist doing most of the graphical work together with a mspaint scribbling shitter
there ARE indie games that have really good graphix, but that kind of thing varies a lot depending on each developer's own skills since they are usually 1-3 man jobs
which is why undertale has overall very mediocre graphics but really good music, character designs and a engaging story
you also have owlboy which is kinda the whole opposite, game looks beautiful but everything else is more or less forgettable
