I think it would be awesome if you could also add a camp to some of the quest areas that are like a preparation camp. The adventures essentially go to the camp to prepare for a big battle like a boss fight.
You could control when to send out the adventurers that are at this camp so it can be a way to build up a group instead of having adventurers slowly trickle into one of the tougher fights.
So the autosave every 30 secs thing obviously doesn't work... Ive been playing for quite some time and Ive rebirthed a handful of times, but i haven't refreshed my browser cause I just leave it up when Im away. I was just shy of 1k cp and I had to refresh for an update, now loading up my username starts over at the begining... Guess Im finished playing this. lol
I love this game so far, My only suggestion would be for the top speed. If you could include the effects of drag that would greatly increase how realistic top speed is. As drag exponentially increases the hp requirement for a given speed. It wouldn't be of much effect until you start reaching 250+kmh, but it would remove the ability to reach speeds of into the thousands with less than 10k hp.
Great game! It would be nice to get a confirmation when adding an upgrade that would make you change class levels. also having 1/4mi, 1/2mi, and 1mi races would add a lot of playability.
