Great and unique game! I like how each level gives the player different potions that can be thrown while the player tries to take advantage of their effects! Additionally, the shadow effect as a recall does come in handy because it can be used to propel myself towards the objective which I thought was interesting!
Some feedback that I would give is that at the beginning of the game, it was very confusing on what to do and it took me a few minutes to complete it with the help of the shadow recall. Additionally, the staff cursor that I see felt like it added to the confusion at the start, and I think it would have been better to switch it out for a potion. Maybe the potion that you are currently holding could be the cursor instead (If this is possible).
In any case, I loved the game mechanics and I think you did a good job putting shadow and alchemy together!
