Dome defense

This is a redstone minigame I made. It has 16 rounds each getting harder and harder. Once you complete all 16 rounds there is a boss battle. 1 or 2 players.

Rules:

Play on adventure mode
Play on easy
Don't break the dome/glass (because you can break glass on adventure mode)

If you find any bugs put them in the comments or else I won't fix them.
Please leave a comment after you play the map to help me with future maps
