Deltatraveler

Deltatraveler is an RPG fan game developed by RynoGG based on the "goddamnit Kris where the hell ARE WE" meme that uses chapters like Deltarune does but swaps them out for sections.

You play as Kris with Susie tagging along when you wake up in the world of Undertale, from there you will get an Undertale-like battle system but Susie will have magic instead of acts, however S-Action will be her variant of ACTing. You end up playing through the ruins for most of the first section.

From here you can choose 3 routes which you can continue in the next sections:

• Pacifist - You do not kill any enemies or goddess you come across, choosing to spare them all instead
• Obliteration - You go out of your way to kill as many as possible, gaining lots of EXP in the process
• Neutral - The middle ground between pacifism and obliterating.

Eventually you come across Noelle who joins your party as you soon enter the world of the second section, Earthbound, which places you in a green area.
