This team immediately deserves huge credit for having the courage to take on a serious and meaningful topic-what would a person do if she had one day to live? It is much easier to try and get some laughs or to show off a clever idea, which is what most teams end up doing. The difficulty for a team which tries something deeper and more serious is that the margins for error are small, and even smaller given the short timeframe.
After taking all of this into account, this film was a great achievement and the team should be proud. The idea and the script and the acting were all great-taking into account the inherent difficulty factor.
I hope that this team continues to try to take on difficult topics, rather than taking the easier options. If you do, I suggest trying to delve even deeper into the characters' thoughts and motivations- and then their actions-given the circumstances they face. If you do this, you may find that it solves plot issues such as those identified in other reviews. It may also mean that it is not necessary to actually state your message in writing at the end of the film. A well told story conveys the message itself.
