Hi, thank you for trying our game!
The extra pixelation was not intentonal but a bug we didn't have time to fix. I know it's not the best solution, but you can wait a few seconds until you lose all the lives and the level will end, then lead you to the gaccha, where you can navigate to all the other menus.
We will keep working on the game, so please come back to try it after the game jam rating period ends ^^
Thank you for your feedback!
