Crashed for me pretty quickly, sorry :(
idk why that happens. it only happened once for me when my brother was playtesting but i couldnt replecate it.
Don't be discouraged! You're obviously motivated and I bet you learned a tonne.
It isn't clear if time shifting is working as intended (it feels like I get stuck after shifting 3-4 times).
i think it might crash if you hold the button because it tries to start another time shift during the animation.
