1.) - If you do so, please add a maximum speedlimit and a maximum of, for example 5-8 clicks.
2.) - Great Idea, makes it kinda more realistic. But don't make it too muzzy - low/high-bound == -10% / +10% 3.) - Need to be tested, can't decide now wether this is good or not. Maybe you just disallow him using 'sprint' - Using sprint will cause loss of the puck. ( not instantly )
4.) - WTF, are we in a noob game? NO NO NO!
5.) - Very bad idea, though I don't like it at all, takes the "tag" fun of the game imo.
6.) - WTF, we are here for playing Ice Hockey ! ( maybe just - "who is the fatest in typing ? type -$random_string$ to get the puck ( just 1 string character. )
