If the player uses invisibility skill in order to run around unnoticed between
enemies, the game may become unbalanced and too easy.

One solution to this may be to have high class droids 6xx+ ignore the
invisibility of tux and attack him nevertheless.

Perhaps we should make cooling item-addons more expensive.

If we have a balancing issue with invisibility, the solution is to balance it better, not make it worthless ;)

in the end part of game the heat is no problem, money isn't a big problem (just
tried to go for a walk into desert valley with exterminator and got 1300
circuits in 7 minutes), price of invisibility source is 600
with >15 s of invisibility you can easily go somewhere, kill some bots, go far
enough to hide, get invisible again, go back etc. (basically the same like
normally, just without bots trying to kill you)

possible solutions
- make some bots ignore invisibility
- make invisibility shorter, more expensive, produce more heat etc.
- using weapon breaks invisibility for a while (bots shooting to place from shot
was fired, moving to that place)
- getting into contact with bot breaks invisibility

Raising priority, we should get this fixed before the next major release in my
opinion!

    enemy: make some droids attack tux even while he is invisible.
========================

Closing this issue: Now some droids attack tux even invisible!
