This was an idea I had:
Me and JNZY would make a minigame in 1 hour.

I made a simple maths question game. The questions are pretty simple because I ran out of time. 
JNZY built a game of Ender Golf.

Here is a strawpoll should you wish to vote for a winner. If people don't vote we will judge by views / downloads.
