YIIK's first public release was on January 17th, 2019, and has had numerous updates over the years. Some were small and fixed bugs and had some tweaks, while others added new content.

For versions pre-dating 1.0, check out the Development History page.

1.0[edit | edit source]

1.0 was the first build for Switch. [Citation Needed] 1.03 was the first version for PC. [Citation Needed] PS4's first verison number was odd, as it displayed both 1.01 and 1.03 on top of each other, giving it a warped appearance. [Citation Needed] The game released on January 17th, 2019.

Not much is known about the 1.01 and 1.02 builds. 1.01 was likely released a day after release, as seen in a livestream from January 18th, 2019.[1] As seen in the stream, the Save menu was changed from the 1.0 build.

Version 1.04 does not exist for the PC version, and it's unknown if it existed for the console releases.

On January 24th, 2019, a new branch was launched that balanced the combat. The access code was "youneedtoletmeinside" but it no longer works.

1.05[edit | edit source]

Released on January 28th, 2019.

This patch greatly increased the overall speed of battles. EXP rewards from enemies were increased, and some enemies were given a bit more HP.

The exact changes are unknown and these are rough estimates of what they probably are. They could be wrong.

  • Text can proceed much faster.
  • Control Stick movement is a bit smoother(?)

  • Aliens now have separate stats for the Mountain Trail.

1.05 received a hotfix on January 29th, 2019, which fixed a bug where the opening questionnaire's lines were mixed up. Once complete, the game would softlock. This hotfix also introduced a major bug where entering a Monster Den would softlock the game.(?)

1.06[edit | edit source]

1.06 initially released on January 31st, 2019, and got multiple "silent" updates which didn't change the version number. The changes aren't entirely known. These updates added Chad and the first remnants of the Old Frankton ending.

Apr. 15, 2019[edit | edit source]
