If a fluff ball bound for one exit gets knocked into the other exit, it counts as a hit.
If Reimu is killed by the very last enemy left, the game treats it as a clear.
Bugs
- It's likely intentional rather than a bug, but the force of a fluff ball pair splitting apart can send fluff balls across solid walls.
- If you try to add a new tower while Lily is on screen, the game may complain that it would block the exit ("STUCK"), even if it wouldn't.
- Rarely, the game will glitch, and give the player thousands of points & power for defeating an enemy.
