While I'm going to be making a different game, here are some ideas I had that I still think are really cool:

1. You are an action movie hero and you have to make something explode every ten seconds to keep the audience from getting bored.

2. The game restarts every ten seconds you have to find a way to beat it very quickly.

3. A brutally difficult bullet hell survival game with checkpoints every ten seconds.

If anyone does happen to use one of these, lemme know, I would love to play the game :)
