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.
