Some of you make these crazy maps where you see how fast you can click or make maps where it has 10's of thousands of creeps.

That is perfectly cool. I encourage different maps. Just keep this in mind... Flash only supports up to 64,000 characters in a string variable. Each time you build a tower, use a powerup, etc, I add this data to a string to record it (might be about 5-7 characters each). So, in a normal game the string might end up being 500-5000 characters long. This causes no issues.

However, in some 'click fast maps' the string exceeds the 64,000 limit in flash and therefore causes issues and your score doesn't save. This is beyond my control as it is a limit in flash, not my game.

So, if you score doesn't save in maps like these, i'm sorry, but blame the map creator, not me :)

So what would that make the max score possible be?

Sounds like you need a few more strings :)

its possible to make such a map last 20 sec for example. that does it, too. not wasting hours on damaging the mouse...
or if such a map should last for 20min, calculate, how many power ups are realistic to spend during that time.
but it's useless to send 1000 creeps with 1000 powerups, of which one can only spend perhaps 10'000 in the given time.

Why can't you just use multiple stings.. That should be quite easy :/

it isn't. but when you balance such a clicktourny, there's no problem. if that was fixed by mor lists, another one would find a wired setting to crash it again. there really is enough room to make a good and exhausting click tournament...! just calculate a little
