It's come to our attention that a game freezing glitch halts progress after the first Bowser cutscene in version 1.3. This will be fixed with version 1.4 (which also fixes a few minor bugs) as soon as we get our comptuer with the Mario project files working. As for now, there isn't any else to do but wait. On the bright side, for all of you who are asking, your save file WILL ALWAYS BE USABLE with updated versions. Sorry that this happened, but we assure you it will be fixed in the near future.
