Good games under 4 hours long

I've had such gaming ADD lately, that the games I seem to enjoy the most and actually complete, are those that are completed in just a couple hours (though many have replay value through unlocks, different modes, etc). Even if they're not the best games, it's nice to get a game "out of the backlog" and actually finish something. Care to share some decent games in this category? I'm sure I own some others. Here's some that I've completed.

• Bleed (1.5 hours)
• Deadlight (4 hours)
• DLC Quest (1 hour)
• eXceed - Gun Bullet Children (1 hour)
• Limbo (3.5 hours)
• McPixel (1.5 hours)
• Noitu Love 2 Devolution (1.5 hours)
• Shatter (3 hours)
• Thomas Was Alone (3.5 hours)
• To The Moon (4 hours)
• VVVVVV (2.5 hours)
