ok dude sorry about the lang i can t speak english very well and it was my first one and ty for ur comment :)

I think this is a fun map to play but there are things that you can improve, I'll make you a list ; 
- Grammar in the map
- Decoration
- Instead of using sign use command blocks
- Don't give a fire resistance you can just swim to the next side and easily finish the wave 1
- Make your parkour harder
- You can't destroy obsidian with TNT
- The creepers at the obsidian wall don't spawn
If you improve those points your map will be way better! :)

hey guys thats is my firist map pls put ur comment after playing ...ty...
