Body
The problem is that you don't create new enemies from time to time, but just shift the same enemy further away on its explosion (i.e. call <code>recycleEnemy</code> method). This single enemy is spawned only once: <code>spawnEnemy</code> function is called in <code>init</code> method only with argument <code>1</code>. You should rework enemy spawning algorithm. Below is a pretty good sample, which increases enemy spawning rate: <ol> <li>Remove <code>number</code> argument from <code>spawnEnemy</code> function: spawn only one enemy</li> <li>Change <code>Enemy.prototype.recycleEnemy</code> function to remove <code>this</code> from <code>enemies</code>. Be cautious: if you'll call this function inside a loop by <code>enemies</code>, you will need to decrease counter to make sure that you won't skip next enemy: <code>--i</code></li> <li>Add a <code>function getSpawnCooldown() { return 100 / spawnAmount; }</code> (100 is approximate constant, you can variate it to change initial spawning rate)</li> <li>Add a variable <code>time</code> which means the number of effective <code>Loop</code> calls from the beginning, defaults to 0</li> <li>Add a variable <code>lastSpawnTime</code>, set it to 0</li> <li>Inside <code>if</code> block of <code>Loop</code> function, add lines: <ol> <li><code>++time</code></li> <li><code>if (time >= lastSpawnTime + getSpawnCooldown()) spawnEnemy();</code></li> </ol></li> <li>In <code>spawnEnemy</code> function, add a line: <code>lastSpawnTime += getSpawnCooldown()</code></li> </ol> Generally, you should better structurize your code. At least, split it to several js files which are responsible for different parts of your application.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
