i like the whole idea (including the pond), but maybe the pond should only heal you like plus 50 total until you die and then you can go back and it'll heal you back to +50........but it should be surrounded by trees and hard to get to........so like maybe there could only be one entrence and one exit.......so it makes it harder if an enemy is inside or comming in.....
.........but all in all i like it
cause i HATE cold places........and maybe on the planet there could be wild animals runnin' around that you could kill for fun
but you would only get like 2 exp from em'......or none.......but it'd be cool seein' like alligators and snakes crawling around inside the jungle....make it more realistic
