This is the first real update after the release and includes:

FireBots - A shielded robot with a flamethrower you don't want to be near for very long! Appears from level 15.

A proper pdf manual - Will help to explain the concept of the game more in-depth and help you get started with making spells.

Explosions and wreckages - The wreckages will now look grittier and more detailed.

Some balancing tweeks has been done as well, including faster energy gain to minimise the times you will stand around just waiting to recharge. More enemies has also been added on later levels to keep the action up. The ArtilleryBot will also appear a bit less than before and has been made a bit weaker.
