Hi developers. I've played this game for since the first beta version. But some recent changes since build 30.12 I guess really annoy me. 1. The changes on exertion system just take all the fun away because It stops the fluency of gaming. I don't know how long will it take to regenerate again. Average man can run for 1km without any rest and regenerate within less than 3 minutes (How about Marathon). So please don't make this a huge limitation for player's activities. And it is also not realistic. 2.Frequent negative factors. In the newest version, I feel easy to have negative emotion.. anxious, nervous, nauseous...etc. The game is just changed to looking for tea bags, coffee and all kinds of pills. Surviving from zombie and building is the main theme, but not those. You may have bad emotion but not that frequent! The above fact really annoy me and it deprive me of the original fun. Sorry for the poor english.
