The nicest thing about it being in HTML5 is that messing with it's variables it's really easy. To make it harder, you can (for example), load the page, open the developer console, type ZType.WAVES = {EXPERT: { wave: 0, spawn: [], spawnWait: 0.3, healthBoost: 0, types: [{ type: EntityEnemyOppressor, count: 3, incEvery: 4 }, { type: EntityEnemyDestroyer, count: 5, incEvery: 2 }, { type: EntityEnemyMine, count: 10, incEvery: 1 }] } } And then start a game on expert mode. You can mess up with the values to make it harder/easier.
