Great job - I had fun playing it. I was glad to get the big clicking radius upgrade but it makes the beginning levels a little too easy. I was also hoping for an auto-click upgrade to give my finger a rest.
Thanks for playing! There actually is already an auto clicker implemented (right click to toggle), I think it's in the tutorial graphic, but I wish I had implemented some sort of visual reminder or indicator during play. I added the auto clicker on the last day and ran out of time fixing bugs.
Yes, you are right, the note about the auto-clicker is in the tutorial - it's the first item... in bold! I'm sorry I missed that. I played it again with the auto-clicker on and the game had quite a different feel. I like both styles. Thanks again!
