[h2]Regarding Nintendo Switch Support[/h2]

At this time, we have determined that the multiplayer experience on Nintendo Switch has not yet reached the quality level we aim to deliver.
As a result, we have decided not to proceed with a Nintendo Switch version for now.

We sincerely apologize to everyone who was looking forward to it.
Our highest priority is delivering Ratatan in the best possible state, and we are focusing our efforts on optimizing the supported platforms, including Nintendo Switch 2.

[h2]Reflecting on Early Access[/h2]

Throughout Early Access, we have received an incredible amount of valuable feedback.
From balance adjustments and roguelike structure improvements to event design and multiplayer optimization, we have continued refining the game step by step.

Thanks to your support, we have finally reached this milestone.

We are now fully focused on completing the final stages of development and preparing for the official release.
We will continue pushing forward toward launch and sincerely appreciate your ongoing support.
