Such an awesome idea! With a smooth and clean art direction and easy to understand instructions on how the game works :3
The puzzle itself were nicely tricky. I needed minimum 2 tries on all of them. And i loved that i was able to move the light after the first puzzle, which opens up so much more on puzzle possibilities :D
Im amazed at the shadow animation in general and wonder how you did that so that is runs correct from different angles :D
I felt like a reset option as button would be nice, after i noticed that my potion steps have been wrong. Which also would have resetted the 3D objects.
And it took me a bit to notice that i could stop, maybe an ui icon as stop sign when its stopped would indicate it nicely that the stop exists. I skipped over the stop often at first when i switched between reverse and play. But maybe that was also me being dumb, when i didnt see that it can stop ,:D
Some mechanics seem to have a cooldown which is nice to avoid double tipping, but it feels like it could be longer on the cauldron. I was able to spam create wrong crystals with extract.
I liked that the different potions and items had comments, which made them more unique :D. But I feel like i found a bug on it. I looked at a Potion and didnt understand what it was at first so after the dialog disappeared i looked at the ground and then again on the Potion. I had to look at the spoon or something else and then again on the specific Potion to get the dialog again. Looking at it, then at the ground or just not at an object and then on the Potion again didnt show the dialog again.
In total, its an awesome game and was very fun. :D
