javascript bombing

i wrote a javascript game to train the target-numbering:

what's the goal?

 

Any manual? But imho the shortest time i spend on bombing the better time i got, which is not depending on my hits or closed field

 

close the field.
important: the tower must be down too.
if you click with the mouse on an already closed target, or you miss a target, your errors increase.
more errors => less downtime.
more hits => bigger downtime.

Richtig: amount of hits.
Falsch: amount of misses.
Rate: percentage of hits/(hits+misses)
Sekunden: elapsed seconds
Hit/Sec: hits per second.

 

at "Help" you read:

Click on "Select" to choose one of three Maps.
Click on "Fly" to start.
Click only on open Targets. Otherwise the next downtime is reduced.
Even the Tower must be down to close the Field.

i don't understand.
the downtime-formula is at the moment:
20 + elapsedTime / 5 + hits - misses * 10

 

anyways, targets are closed for 15 seconds max, so it's impossible to me to close the field

 

i'm sorry, but the values should vary between 10 and 100.
i don't know, why my javascript is not okay for you.
i changed the formula to use different constants, and not allways 20.

 

i translated the game to english.
if the downtimes are too low, start a new game by clicking on "Fly".
there is now a video to see, how it should work.
