Wow, great game! Those big monsters was so creepy, hated being near them haha :D Really impressive to create a metroidvania in just a week! I really enjoyed it, the story was very sweet, the music and atmosphere was really great. The only feedback I can think of right now is to shorten the animation when you open a door, started to be a little annoying at the end when there was doors everywhere :D Overall, awesome work!
If you have the time I would love it if you gave my game a try too! :)
