I'm always a fan of minimalist design and indicating health in a world element is a particular favourite. Well done.
I enjoyed playing through this and wanted to, nay, needed to see it through to get this little guy to the big tree in the distance.
The end section I was unable to run or plant anymore (not sure if this is intentional), so that section leading up to the final tree became quite tense as I had to walk through fire.
Well done on a really good game.
