PlusSurvival

Hi, Im new to this whole "make things for other people" but i think you might like this. I call it PlusSurvival not because I like pluses but because in the middle of the spawn, there is a plus below you. DO NOT USE MODS OR ANYTHING LIKE THAT! I'd be happy if any of you would like to make a letsplay video from it. Umm.. i used singleplayer commands to make it, so if you have any cheats like instant mine or fly on, comment and ill fix it. CHALLENGES:
1: Make a house
2: Make a path to the "wool island"
3: Make a way for mobs to spawn
4: Try to record your progress
5: Put screen shots of what you did in the comments
6: Make a Skyscraper
7: Make a city
8: Open a server with your city as the map
9: Invite me to play with you :)
10: HAVE FUN
