Gamemaker Day 16

Today I learned how to make my character to switch room, when my character did something.
What i did : I did when my character shot a enemy, it will go on to the next level, but there are a problem that when my character shot one enemy,it will just switch room with all the enemy still in first room.

The next day I'm going fix the problem that I had : game will go on to the next room when all the enemy are destroy.
