Also, just retired, and started up as a mage...and I got a treasure chest after only playing maybe 15~20 minutes...I'm sitting at 40 minutes of game play and still haven't taken the chest out...in fact it's sitting at 60% health right now. I hope whatever is in the chest is awesome
When you get to level 100 the vet page just says retire instead of what level you need to be to retire, and after you do that once the level does change, but I would guess if you found it once you *might* be able to find the retire button again.
I actually found this to be one of the easier launch games I've played. I was able to reach the end withing 12 days. I focused on buying energy and corn. When your going up instead of trying to grab the most stars try to never pass up corn because I was able to get back up to max energy from half with just 2 maybe 3 corn.
for level 19 it's easiest to get it straight from the menu when it first tells you about the cannon just get rid of the round piece as fast as possible. If you miss exit to the menu to try again.
Past level 19 or so it got really laggy for me. I would let go of a ball and it would keep growing for a few seconds. It got so bad I couldn't continue playing past level 24. Otherwise I enjoyed playing up until then
