Box 'N Bash (LD34)

WARNING: MINOR BLOODY ACCIDENTS DEPICTED

Created for Ludum Dare 34

You've been hired for an important, important job: stacking crates. The foreman won't tell you why it's so important, but he'll make sure you have all the "encouragement" you need to get it done.

Using the left and right arrows, aim the crates at the top of the screen before they fall into the pit below. To reach your goal, you need to not kill the Box Goblins (tempting though it may be) -- and be careful of Boom Boxes!

As long as one crate is stationary on the tape line for long enough, you win, so there are some less traditional methods of pulling that off.

Here is its Ludum Dare page.
