We're planning on submitting an Ashcan (hope that's ok?), because the scope creep has crept and whilst we now have a playable version, it's not going to be pretty and all singing and dancing in a week (or two).  Though defintiely nothing wrong with more time. 

My partner and I should be able to get the core bones of the project done by the due date, but we've also suffered scope creep and wouldn't deny an extra week to cushion ourselves and give my partner more time to work on artwork, we'd also be able to get another playtest in at least and prevent the dreaded end-jam crunch,

Okay great! Went ahead and added another week to the jam!
