The map flow was really fun. I liked the layout that indicated the next goal in a very organic way, nice work!
The pixel art is a bit inconsistent especially regarding the player and the enemies.
Gameplay wise, the enemies are fun to fight and bait into attacking but the first (the boss I got stuck on) has no window for you to attack and its a little too aggressive for a first boss.
Regardless the idea of scaling a forest of mega-trees with enemy megafauna was really cool!
