After playing Undertale for the first time at the start of the month, then starting Deltarune later, my journey is finally complete after finishing Chapter 4 today. I had a good time- and despite being spoiled on most things story wise it didn't deter my enjoyment whatsoever and a majority of the actual gameplay ended up being new to me. I do look forward to being able to play Chapter 5 fully blind at least. But most of all I can finally cast off the shackles of being a filthy secondary.
