The final level! This is the one where you dexterity is needed the most!

There are six symbols in the game: → (Red symbol)
↓ (Blue symbol)
Λ (Green symbol)
V (Yellow symbol) ֍(Lightning - clears one symbol off each ghost on screen and used at the end of the final boss sequence) Note I can't find a Unicode character for lightning but you know what it looks like. ♥ (Heart - restores one heart)

Every level has a set of waves. The next wave appears when all the ghosts in the current wave are dead. However, some waves have timings so ghosts at a certain time - there's no way to speed this up. (a quite clear example of this is in Stage 2 before the boss) Therefore, you should focus on the last ghost(s) of a wave to get a good time. As general advice, you should just spam the symbol that comes next (you can look at this guide) and then read the rest.

The first ghost(s) in a wave is named Ghost 0.0s. If ghost(s) comes at a set time after these first ghost(s), it will be named after their respective times (e.g. Ghost 0.5s, Ghost 1.0s). These times are rounded to the nearest 1/10s due to awkward 30FPS recording. After you clear a wave, it takes 1.7±1.0s for the ghost(s) of the next wave to appear, whose level depends on certain stages, being hit by the last ghost, and if there is an upcoming boss.

I also recommend you play the game several times before reading this - that way you don't have to look at the reference every step of the way.

Notes: • Don't choke :P • It takes 0.6s for the final boss to transition from ghosts to boss pattern. • The time it takes to draw the final symbol to score screen is 14.0s
