This is a really cool concept, making it like the 2d Zelda games but you need to plan / preserve your sword swings. I also never heard of GDevelop, so it cools to see something not made with Unreal, Unity, Godot, or a self made game engine. I will have to check out GDevelop so time.
I think the only main problems are that the GUI is a little messy. It would be cool to see the potions as icons instead of text. Also, the Player sprite did look blurry instead of pixel arty.
