All enemy classes, boss flow, and kill rules
Baseline zombie. Stable movement and normal castle DPS when it reaches the wall.
Faster push unit. It reaches the castle earlier and forces quick target swaps.
Tank unit with multiple HP pips. Slower movement, harder to remove under pressure.
Explosive unit. If it touches castle range it detonates for heavy burst damage.
Only one can exist at a time. It enters, parks on the far left, and throws large rocks at the castle every 2 seconds for 10 damage.
Appears before a new week starts. Small enemies are cleared, boss enters the stage, then the 50-note sequence appears.
