Thanks for playing!
The idea was to make it hard and punishing when you are very loaded so you have to plan your route when you want to collect a lot of stuff.
So for example, you go for things that are hard to get at the beginning and leave easiest at the end when you are pretty much full.
Also making it back with a full backpack should feel super rewarding!
I am thinking about adding a local/online coop&versus and exploring idea more
