Hello everyone!
To celebrate HYNPYTOL's release on Nintendo Switch, the major 1.5 patch has been implemented!
Various content, features, and quality-of-life improvements have been added. Additionally, the trailer has been updated!
Here are the details:

The ‘Immunopedia’ has been newly added. Discover the characteristics and stories of various immune friends!
New visual effects have been added. Experience the displays of old-school gaming consoles and CRT monitors!
To commemorate the Nintendo Switch release, new borders have been added. They are the foundation upon which HYNPYTOL stands.
Cute updates have been made to the ‘GameKid’ border. Check out the Easter Egg achievements!
The structure of the Thymus has been remade. Did you know the T in T-cells stands for Thymus? They're named for their final tests in the thymus!
A control helper popup now appears in the Bone Marrow! No more confusion… hopefully?
The structure of the Memory Center has been remade. It’s as intricate as its name suggests.
Adorable name tags now appear in dialogue! No more guessing who’s who.
A ‘Skip Dialogue’ option has been added for multiple playthroughs. Just high-five your way through!
Extras have been added to the pause screen and title menu. Check out the codex and credits mid-game!
A special new song has been added exclusively for the Immunopedia! Rumor has it there are different versions depending on the situation...
The entrance design of the Filter Region has been tweaked. They say the cells have added festive headgear for their sports day!
The Paradise of the Surface design has been altered. Enjoy a fireworks show over the nighttime sea!
Controller support now includes satisfying vibrations. Feel the thrill in your hands!
The visibility of the Filter Region has been improved.
The structure of the Lymph Nodes has been refined.
Some Time Attack map structures have been improved.
The difficulty and level design of the Infected Cell area have been slightly adjusted.
Visuals for certain maps have been enhanced.
Starry letterboxes now appear in fullscreen mode.
The Korean font has been updated.
The issue where Chinese did not function properly in the initial language selection screen has been fixed.
Certain dialogue misprints in German have been corrected.
The problem where Workshop uploads were possible without clearing the levels has been resolved.
Certain UI misalignments in the Level Editor have been fixed.
The Level Editor now supports controller input.
ESC not functioning in certain situations in the Level Editor has been resolved.
The inability to input a title after saving in the Level Editor has been fixed.
This major update for HYNPYTOL will (probably) be its last.
Thank you so much for joining us on this long journey through the immune system!
We couldn’t have come this far without you.
We hope this patch brings the world of HYNPYTOL closer to your hearts.
Please help spread the word so more people can explore the immune system!
