I have a minecraft minigame idea is this possible to create?

So I have this awesome idea for a minecraft minigame. So we build a tower that goes about 150 blocks up (just a estimate) and in the tower we place blocks randomly to climb up the tower like Parkour but at the same time lava flows and fills up the tower causing the players who are slower in the parkour race to die. So its basically a race game to the top but at the same time lava fills up the area so it makes it somewhat harder.

Sounds like a good idea for a minigame. I would play it. Sounds like it would take quite a bit of work for the lava to slowly rise. Check the minecraft forums for help. http://www.minecraftforum.net/...forum.net/

Guess what? I found a site that's giving Minecraft gift codes away for free! http://freeminecraftgiftcode.net

Your minigame might be difficult to make since one could just build one tall pillar all the way up and win everytime instead of randomizing it.
