It's your own fault if you can't think

I mean through this chat command
/think

I'm sorry, psychic abilities can't be programmed into a game.

Just because you are incapable of thought doesn't mean that the rest of are. Besides if we made thought mandatory who would play Highlander?

What is /think exactly supposed to do? Should a chat message like "* Wuzzy thinks … Do not disturb!" appear?
If yes, you can already do this with the /me command. The syntax is:
/me {Text}
This will result in:

Replace {Text} with your text. Hedgewars replaces {Your name} with your name for you.

So if you say /me thinks … in the chat this appears in the chat:

So it seems your requested feature has already been implemented. Well, sort of.

Slightly related to this are the "thinking bubbles" which can appear above your hedgehogs. You can let appear a thinking bubble above your current by writing this in chat:
'{Text}'
→ your current hedgehog thinks {Text}

/hta {Text} → your current hedgehog thinks {Text} at the next attack

I mean like worms armageddon. Move it back!

Well then, it's a shame that we aren't Worms Armageddon isn't it?

WTF? OK, lock this thread NOW!
