Toby's a gamer,

He created a Game hack of one of Nintendo cult classic,

He created several musical pieces for a comic about Games (among other things),

He wanted to create a game about his fever dream, but were unable to do so since it's too ambitious for a small dev team to handle.

So yeah, these are some of the good reason why Undertale was developed the way it is.
