ok so, the game is not bad overall. I liked the idea. The art was pretty good; i liked the different environments. The audio was nice too. But the gameplay wasn't that nice.
For starters, like many others have mentioned already, fortune cookie + bridge of the void combo is just too OP in elimination mode. In fact, in every mode, it's wayyy too OP... And this strategy below, basically guarantees a win in any mode when playing as fortune cookie:

If any cookie somehow manages to not step into the void, which in this scenario and from my experience of playing the game, the cookie will be on the third plank, never reaching the fourth (unless fortune cookie but im always playing as fortune cookie). So if the cookie survives the bridge, you can just quickly add a cannon to the second lane, capturing the cookie from the third, sending the cookie back to the second lane bridge to fall into the void. Hence this effectively becomes a foolproof way to win. Of course, the broken planks lane positions are random, but the strategy will still apply.
Next, I'm not sure if this is intentional, but the random obstacles mechanic doesn't seem to spawn anything other than the bridge of the void and the river. Imo if the cannon or the conveyor belt also spawns, it'll make for a much more interesting gameplay, cuz like- the cannon is pretty much the only thing that can take fortune cookie out from what i've played. Having the cannon be auto-spawned means you need to use the conveyor belt to make the fortune cookie avoid the cannon.
Moving on, at times, the gameplay can feel kinda stale ngl. Like when waiting for the cookies to get to the next obstacle, it can be quite a long wait, especially with multiple rivers having auto-spawned... I don't really know how you can fix this tho.
Anyway, I also found this bug where a cookie can get stuck whilst playing (rolling cookie is stuck):

And well in elimination this means you'll never win and will have to quit :/
Also, the outline of the text in the tutorial is kinda weird.
Next, the camera panning control felt rather sluggish, like the movement kinda accelerates and decelerates a little too slowly. This is not really that big of a deal but well it'd be nice if it was snappier imo (i added this feedback for the extra bitterness you requested :var:)
That said, I liked the amount of polishing you've managed to squeeze in. And I do like the different obstacle mechanics in the game, but it's just that the way that certain things are implemented... allows for the "foolproof win strat". If you balanced the fortune cookie's OPness and patched the strat, i feel like this game can be pretty nice.
