Great music! Great art and animation! Lots of mechanics packed in and very nicely polished.
I took me a little bit to figure out the strategy. I could have started with the smaller map size and highlighting, but I just jumped in. I think not being able to gain more than 100 HP became the bottleneck at the last stage. Luckily, I was usually within two tiles of something, though it sometimes took a lot of searching and some planning ahead. I liked that the world wasn't flat, but some of the larger differences in tile height added to a difficulty in playing, rather than just being a nice aesthetic.
Anyway, I scored 420 - I'm happy. I might try another round later, too. Great submission by a talented team!
