Thanks for your feedback!
Cool that you actually made it all the way through :D
Yeah, we have a whole system mapped out, you're supposed to have HP, a thirst and a hunger level -> need to hunt rabbits for food, get water for thirst (rabbits already drop a dead rabbit when killed and you can pick it up), and the changes between the elemental states (fire - neutral - ice) are supposed to be linked to the story and the progress of the game. We already designed assets for a bunch of things you could use as weapons and also med kits from the wreck to patch up your HP etc., but as we said in the description, this was made in less then 3 days, so unfortunately this is nothing more than a bare minimum to be able to do something in the game, but it's all we managed to implement in the shortened time frame.
Probably we focused too much on making neat animations and music for our ideas, when we hadn't yet implemented them code wise and then time just ran out on us in the end...well, lesson learned for the next one, I guess (:
