I very much like this game, though it has issues, not least the less-than-smooth movement and the grey screen of death that I've managed to get occasionally. Pause exploiting should be gotten rid of; fishing is easy enough anyway. The inventory should be re-arrangeable, and items should go to existing stacks over empty spaces. There should definitely be a save feature, as well as a log so I can view past messages. Temperature should have a little more effect, exponential increase would be nice as it forces players to make short forays during the daytime, or simply stay indoors. It's pretty similar to Notrium, actually, there might be a few things in there you might want to incorporate here :).
Overall, a good concept suffering from not-exactly-perfect execution. I wait for a save feature... and after that, sequels. 4/5, especially since I haven't seen any game of this type in flash yet.
VERY challenging, but fun. Omegaone, you have to finish level 2 to get the bronze. Took me half an hour and a sore back T_T. 5/5 for being addicting xD
