Really interesting day/night mechanics. The moon bridge was super cool! Awesome work on the boss fight too! I really enjoyed my playthrough and the alchemy brewing system was quite unique. Love the sunset sky panorama, and the art was all great :)
One thing I've learned about platformers, gathering feedback from my own playtesters in various game jams is to increase friction/acceleration a bit more than you might initially want to. Even if it doesn't feel quite as fluid, giving players more acceleration and predictable friction is usually better and lowers the learning curve a bit. (I tend to make my platformers feel slippery too, but since I'm playtesting it constantly while developing it, I quickly get used to the 'feel' of it, whereas someone picking it up for the first time will not have that same experience and feel out of control at first). You'll see in my video most of my deaths came from the friction and acceleration not being quite as tight as I expect and mistiming a jump or sliding off the ledges.
That's quite a detailed note, though, and overall it did not detract much for me. I enjoyed getting to learn the game feel from some trial and error. :)
The 'metroidvania' aspect was also really cool! I liked how you placed the recipes in locations I would find naturally and that made it easy to figure out the next objective. Really great job, especially with 3 mo. experience in Godot! Very impressive! Lastly, my favorite part was the fireball vollley. Really fun to use on the boss fight. Pew pew pew!
