Great idea! The fact that something odd changes every time you open a door makes it really interesting, it made me feel curious every time I saw one. The combat did need quite some testing until I got the timing, died quite a few times there haha. The audio is very fitting, but in my opinion the different graphics styles feel a bit odd - there is a lot of pixel art but the characters have a hand-painted look, while he HP bars are flat-colored. The combination looks somewhat weird.
The game has quite a few annoying bugs though that kept me from playing it further. The map hitboxes felt kinda unpredictable, sometimes I could walk through a tree, sometimes a tiny rock would block me.
When dying in the later chapters, I got respawned with ~20% HP a few times which made the game very very challenging, but then I got respawned one time with my health constantly refilling. Also the season change made it very difficult to see my HP sometimes.
Lastly, after opening that door on the island and dying afterwards, the game respawned me but froze a short time after, making further progress impossible :(
After some bug fixing this game could be really awesome. Well done!
