i like it, but i think it really needs some tweaking, the basic idea is very cool tho..
instead of every minute you are active it should tick every 1 hour.. for 1 hour of activity without going offline during the session you would get a lil icon like BK mentioned and once clicked you enter a captcha and receive 5 tokens..
time would NOT be on a set rotation rather 1 hour exact from the time u log in, once that hour has ticked the icon would be visible for a total of 5 mins, if it is NOT clicked before the 5 mins it will disappear and the next hour will continue counting
reaching 30min inactive and being registered as "Offline" will reset the timer and you wont get credit for the time spent online
not too fond of the current rewards tho, my suggestion is more along the lines of
100 tokens = 10 credits
250 tokens = 30 credits
500 tokens = 80 credits
these are small payouts but still worth the time taken to click the icon and enter the captcha. we cant have the payout too high as it will just flood the game with credits making donators get less for the money they spend in game and make the gap between seasoned players and new players that much further of a distance making them less likely to stay
at the same time active non donators will still have a chance to earn credits for RM, land etc and players who actually spend time paying attention rather than mindless clicking or "checking in" may also be rewarded for such
this is my 2 cents do with it what you will
