Towelket One More Time 5 (タオルケットをもう一度5～がぅがぅの花嫁～）is a free Earthbound inspired JRPG made by Kanao (Kanashimi Hocchikisu) in the year of 2010.

Synopsys:

Two robots are jumping at the center of the Earth, making the planet constantly rotating. Meanwhile, striving to win her sister's heart and prove her theories wrong, stupid but stubborn dog girl Pucchi is digging a deep cave leading to the Earth core. A global disaster is imminent, and the fate of humankind is apparently sealed... or maybe not?

Towelket: One More Time is a japanese series of free indie RPG games made on RPG Maker 2000 by Kanao, first released in 2008. It features cute graphics mixed with a strange, fantasy-ish atmosphere akin to Earthbound; although with occasional guro and dirty jokes, giving it a charming unevenness. Most of the main games involve aliens invading the world and attempting to harm humans, with the main party being tasked with saving the earth. 

Correct game's release order is: 3, 2, 1, 6, 4, Fury, 5 (the rest is untranslated yet).

Important: this game wasn't made by us (Patchy Illusion Team)! The developer allowed the games translation, however.

Warnings:

Drugs and alcohol abuse, pixelized violence, mentions of sex.
