Finished with a time of 3:42. For someone not great at fast platformers, I'm proud of that.
A couple of things I noticed: The music, while excellent and hype, could be a little ear grating. Perhaps consider adding in sound controls so that people can turn off the music if they want. Also, in the areas where the protagonist mentioned "Anti-Alchemy Coating", I found I was still able to make pillars. Might be an oversight there.
The game overall is very fun and very fluid, with a high skill ceiling if you can master the "pillar jumps" as I like to call them. The story as well is interesting and engaging. Always love a story about a corrupt alchemical organization running the world. The pixel art is incredible as well! Very charming yet conveys the action of the setting phenomenally.
Excited to see more of this in the future!
