Ok great. Thanks!

In the Enemy spawns section at the very top you should find an item called "AI Trigger" drag this on to the map, and When stepped in, will trigger what ever it is assigned to, you can assign an enemy to a trigger by clicking on the enemy you want and finding the trigger. I struggled with the system at first. remember things like animations and doors can also be triggered by AI triggers.

Thanks for the feedback. The reason why I didn't have as much enemies is because I couldn't figure out how to make them all stay where they are when the player is ascending. They all just jump into the laser detector.

Overall, It's well decorated, but first, all of the space in the level that could have been used for some fun combat combat encounters, is just empty. The main challenge at the end is easy and the player is too upgraded for it to pose a threat.
