Very sweet game, love the idea! The potion variety and how they all interact is really cool! The shade mechanic is also very neat, can be used both as a safety measure to go back to if you fall, as well as to generate momentum.
When I got to potion of creation I couldn't beat the level, at least for now, on touchpad, right clicking is a lot more difficult. I also feels unfair that the shape is random, I guess that's the perks of being an alchemist/wizard, you don't know what's gonna happen, but sometimes the platforms just weren't the right size to beat the level.
I also got some weird bug when I threw it under myself I got teleported up a lot, beyond the background tilemap, wasn't able to replicate it.
