Idea Volcano Climb

Pre-words:
Hello everyone, it has been a while since I here on brawl, maybe 2 years now. Well before I left I was extremely active. Some days ago I came up with a new party idea, so I started to build a map and code it. I wanted to keep it simple so I coded it using command blocks. The map is 80-90% done, I just need to change all dirt to stone, using world edit.
Currently I don't have any pictures of the map.
Game:
How to win: Climb up to the top first, you will climb inside of the volcano.
Map: The map is basically a hole in the ground, that is supposed to be a volcano, at the bottom of it there is a small layer of lava that will soon rise to the top and kill everyone in it's way.
How to climb: When I say climbing I mean running or jumping at blocks get closer to the top, I've tested the map a couple of times and it won't be so easy to climb to the top of it. I found about 3 paths that leads to the top.
Catch: The catchy thing about this game is, the volcano WILL be active, that means, once every 3 seconds 1
layer of lava will rise, if you touch the lava you lose. If this isn't hard enough you could make it EXTREMELY hard by adding, knockback sticks. In that case the players can hit eachother to knock them down to the lava/bottom.
Plugins: I don't think this game requires some real complicated plugins, just starting, death and ending events. If you want to make it complicated and pretty much cooler, you could add wall climbing plugins, that makes it possible to climb walls (It's very often hidden ladders). Then you jump from side to side and climbing up, you have to be faster than the lava and not get knocked back by other players.
Spawn: You will spawn at the bottom of the volcano.
Re-Spawn: Personally I think it is borring to watch the others climb from the top while I'm flying up there, but since there are a lot of parkour most players will fall and die, that means it will end quickly. To prevent this you can simply add a spawnpoint. For example: When you reach this or this block you will set a spawnpoint and the next time you die you will teleport to it. In many replies and threads party staff has been telling us that the games should be kept simple and short, that is why I think we shouldn't have spawnpoints.
Testing: If this game gets approved by the server staff and players I want it to be tested to see if it's fun, hard enough, and how much time it takes to win the game. In that case I need about 10 players, staff or members, the more the better (not more than 20-30 though). Please reply to me if your interested, in that case I will add you to a conversation with all interested players. I will fix time and date, we will meet, you will play. Afterwards you will write an essay what you thought about it then we are done. No no no, just kidding, not an essay , it will be more like a normal reply with feedback. You will give it to me and we are done. You will have fun and I will have the honor of saying I created this game...
Comments:
Hopefully you like this idea, and hopefully it will become a party game. I think this game fit in there perfectly. Please reply, advantages, disadvantages, more features, anything.

Tinsten is back!!! Mostly on forums though, I don't liked 1.9 and the other hand thing... I'll stick to writing long replies on forums, hopefully some day I will become global forum moderator =)

The map can be changed.

 

It's a volcano, you parkour the way up, at the walls, at the same time there will be lava that is rising... You touch it you die. Simple

You start in the volcano, at the bottom of it
