I had a lot of problems with level sequencing and getting my cutscenes to trigger properly so I striped them all out at the last minute to at least have something to show. There was an ending cinematic where a snowman appeared out of your ball with the snowman being scaled to the ending size of your ball and decorated with any items collected. That gave a nice player choice of either collect items or make the ball really big as both are not possible in a single 1 min run but maybe encourages a replay where you then go for the other choice. I was also playing around with menu options for the player to select your own time limit for more relaxed gameplay and achieving both choices in a single session, that didn't make it in the finished build either which was a shame as a 5 min timer allowed for the rolling of a truly gargantuan ball.
Unfortunately I don't really understand why the performance is so bad and whether it's being caused by an engine setting or my own poor coding practices/choices.
