This is an interesting idea. There's a neat balance between having to spend "time" crafting and moving to avoid losing. But it seems like the purple always moves if you move right, so you then should always craft, rather than try make some distance. I think that could have added a little bit of complexity to the game.
I did get told I lost a few times even though I could have crafted the machete in the forest tile I was in to then proceed through the surrounding jungle, but I'm sure you've seen that already.
I like the infinite generation part, it's kinda nice to just mess around in.
