We brighten up your day - and the exits. Yes, we made it easier for you to see the available exits! 
We turned on the lights (powered by renewable energy only) . Just for you! Yeah, we know...like in Celeste...blahblahblah....

But where there is light, there is also shadow. The underground and castle areas are not so dark anymore to make life easier for you. The whole level is visible - at least kinda shadow-ish. Alpha transparency, baby!
