I tried hard to come up with an idea that 10 seconds is not a limit and here’s what I got. Actually, the idea is simple: you’re collecting some stuff avoiding obstacles, and occasionally you get a powerup that lasts for 10 seconds for extra enhancement, but that 10 seconds can be too much. During a powerup, you might miss things that you could get when you didn’t powerup, or sometimes the powerup lasts too long that would risk your life. It’s like a drug! This is going to be a simplistic platformer/racing-type game. Let’s see how far I can go with this idea.

Edit: Oh yeah, the game title will be “10 Seconds is Too Long”.
