I've validated the files, uninstalled the game and re-installed it and kept it open for a long time to see if it fixed itself but the epilepsy screen just keeps flashing on screen endlessly no matter what? any fixes?

Я заметил, что уровни 1-X и 1-XN облегчили... Заметил, что когда помехи усиливаются, слышно звучание битов... Я бы хотел эту функцию хоть бы отключать в настройках, или сделать возможность выбора с начала игры... Просто такие крутые уровни выглядят слишком лёгкими из-за этого......

The window choreography is consistently lagging and preventing input at the part right after the first cut scene where the screen starts expanding. This is arguably the easiest parts of the game (and the stage itself too is straightforward), is there anyway around it? I tried playing on fresh restart, reducing screen resolution (thinking fewer pixels to work with?!) https://youtu.be/PUhdJTE6Bl4 Thanks!...

the ending level isnt there anymore, like the little song you got after beating the game? i beat the final boss again but that does nothing

I love when games add new achievements, but please, don't add achievements that require other players (even worse - localy).
