Glad you liked it, but I'm not sure what you mean by "the old checkpoint"
When you fall from the platforms near the end of the game, it is possible to trigger the checkpoint below it setting your progress back. Are you trying to tell me that was unintentional? Personally I thought it was really cool.
It was absolutely unintentional lol
I suggest you keep it in, it kind of reminds me of Getting Over It.
