Could you make it possible to press spacebar instead of clicking while doing a quest? If you need to click, you need to move the mouse to the right place, like the 'OK' button when getting a treasure and spacebar would simply be, well... simpler
"We already expand from 8 to 12 ." Yes, you may have expanded it, but it needs another expansion. Who wants to tie in 12 rounds? Also, if you remark it, bosses are getting stronger, so maybe a little more time to fight them will be nice, especially a boss like Bajaj who blocks a big part of your hits?
You need to decide - is it a completely automatic game when you just sit there and do nothing or are there things necessary to do manually other than clicking "start" or advancing in a quest?
