GIGA Queen stepped on me and I liked it

I spent the past three weeks playing Deltarune, which is both very good and very free. I suck at bullet hell and didn't enjoy Undertale as much as I would have liked to, but Deltarune is a bit more accessible to Casual Gamers™ such as myself.

I'm somewhat mystified by why everyone seems to be obsessed with Spamton, a diminutive ventriloquist's dummy who turns out to be a secret boss, but I'll just have to accept that there are some things I will never understand.

I also want to ask if we're sure, like truly 100% sure, that Toby Fox and Andrew Hussie are not the same person.
