Wow, this was so much content! I liked the movement and the combat, felt pretty solid. There were so many moves, at some point it was confusing choosing between all the buttons, but every skill was interesting and the way we get rid of the corruption made sense with the theme.
The map tool was awesome and kept me in track of what areas I hadn't visited, it is very welcome in a game with such a big game area. I did get all the seeds, the fast travel system was also great but it was hard to keep track of the names of each area to know where I wanted to travel.
All in all, a great game, I enjoyed it a lot, it felt like a metroidvania from the start, and the clever way the new skills open up the map is really well handled. Even though there's backtrack, I didn't feel that I was going around without a reason. The map is fast to traverse and the "road" of getting skills make sense so it doesn't feel like you're going from one corner to the other and back.
Overall, a great entry, the sound and music were ok, the graphics and animations interesting, the vines looked good and were my favourite part of moving around, it feels solid and in general it goes to the vine I want to go when I use it, so it's very intuitive and satisfactory of a skill.
Congratulations, this is a great game!
