Thanks for all the comments, this Jam was a lot of fun! I'll address a few of the issues that people have mentioned here:

Balancing
It's too hard to begin with and that really needs fixing, I didn't have enough time to work on this aspect. I think I'd want the potions to drop a lot slower at the start, and reduce the number of different potions to a smaller sample. Then have the drops speed up and increase the number and variety as the number of recipes completed increases.

Loading
I forgot to preload the game from the menu! And I should've preloaded the shaders and some of the particle effects too. Lack of testing in the browser was the problem here. 

I'm planning to continue working on this game after the Jam judging is complete. Hopefully I'll address all the above issues and get to add some additional features like special potions that will give time bonuses and other positive effects (and probably some negative ones too!)

The feedback is greatly appreciated.

I think I've spent almost an hour trying to remember all the potions from memory in order to get good at the game. Very nice game loop, satisfying and stressful. Very very well done Vex! Thanks for making the game <3

really cool idea and exectuion, the text is little bit hard to read, cos by the time you read when the potion was, its too late to push it to the right spot :D

I think if you solve how to make the player find the potion without reading the text, you've got nice game on your hands

Very intense! :D A really fun use of physics and the mechanics are solid overall. The sounds and art are also nice.

I do wish the potions spawned a bit further from the left edge, I kept knocking potions into the recipe area by accident.

I've never been so stressed :D :D Great work. Really cool idea & excellently put together.

I love the idea of bringing more dexterity mechanics into video games. Thank you for building and sharing!

really fun! think it would have been a tad easier if the potions had stronger colors for me to differentiate them as the font was a bit hard to read at a lower res

Pretty good visuals and like the idea, i did find it hard picking out potions from the list correctly and just mashed stuff in and if it wasn't on the list mash it out. lul.

Ok, I'm obsessed. I'm prolly gonna return to this one after the jam, to play more  :) The art is perfect, the sound engineering is on point. The only POSSIBLE complaint I could have is that it lagged my browser out when loading.  But that's not really your fault at all, if this were a desktop game, I'm sure it'd run just fine. LOVED IT!

Wow, really beautifully designed. All those visual effects are great!

While a little overwhelming at first, once you've learned to constantly swipe everything right until one of the required potions drop, the game becomes kind of endless 😅

Still, very fun, knocking the potions araound and playing with the physics. Very responsive
