Enemies have the appearance of the letter "S". They look the exact same as the Running Enemy, but they stand still.
They stand still and wait for you to kill them, or for you to blindly walk on top of them. The running enemies run straight at you, mirroring your moves vertically.
Running Enemies have the same appearance as the Basic Enemy, which is the letter "S".
These enemies run at you and attempt to run into you, which instantly kills you and removes a life.
The letter "P" resembles the wizard. Their projectile lightning looks like a "Z".
Wizards stand still and shoot projectile attacks at you across a horizontal plane. Touching any of those attacks, or the wizard, kills you.
The Tower looks like a letter "T". The cannon shots look like a "." (period).
Like the Wizard, the Tower shoots projectile "cannon shots", but across the Y-axis instead of the X-axis. The Tower can kill you either by touching it, or when you get hit by the cannon shot. Unlike the wizard, though, the Tower can't be killed, as it is a stage hazard.
