Tip: When determining a time limit, remember that players won't be as familiar with the level as you are. If you normally complete the level with the timer around 100, others might run out of time on their first try.
I made a custom overworld and I put those green path things on it, linking the levels to each other. When I test the game, Mario won't move from Yoshi's house, even though the paths connecting it to 2 other levels is white. How do I fix this?
