An incredible well crafted Metroidvania. Really nicely polished. Mechanics were very well executed.
The only suggestion would be to bring a little more attention that the map is available for download somewhere prominent in the description, with the game not having a built in map. I missed it the first few reads.
I was very impressed with the diversity of pretty much everything. I did not encounter a single bug.
Besides it missing a map, the bombable area to go down below I missed the first few times, seemed it need to be a little precise, but I got there in the end. Pillow acquired with 88% completion :)
Very nicely done... and good luck in the Alchemy Jam :)
