Quoted from goldant:I'm really hoping they let you pick which mode you start. I've only made it into Barrel Escape twice so far.
I don't think it would make sense to be able to choose so I'd be disappointed if they made that change. I think you should have to work your way through them as they escalate.
I've had Barrel Escape lit probably 5 games now, but haven't yet been able to get it started. Can't wait to finally play it.
