Hmm so I understood that I’m supposed to cook stuff and follow the recipes on the wall, but every interaction was really lacking in feedback and feeling very confusing.

First customer orders a burger. Right, there’s a box of hamburger patties, but nothing happens when I press E so I suppose the guy next to it wants gold first. The only thing that looks yellow in the room is a box of round yellow blobs, but when I try to give them to the guy they just float in front of his body.

At this point I thought the game was bugged/unfinished and was ready to give up, but after reading the comments here I realized that what I thought was “gold” is actually the “money” stone in the cash register. So now I was able to make the hamburger and the “fries” for the next customer, but then on the third recipe (a soup of raw egg and nuts?) I couldn’t figure out how to get the white stuff out of the mortar, so at this point I finally gave up after all :)

I got a big old thumbs up, so I think that means I won, haha. This was a pretty confusing experience for the most part, I found myself second guessing every action because I never felt sure that I was holding the right ingredient. Is the symbol on the wall a potato or a loaf of bread? Is this an egg or a chestnut? That kind of thing. 

Systematically, it all works surprisingly well. Even handling stuff like being able to mortar and pestle two ingredients at once, I wasn't expecting that to be possible but it was. Having some small minigame elements included definitely made the game feel fuller, and they were all good additions. For a game jam this is already feature complete, and really does feel like a fairly full package, but some ways it could be expanded on more is if the minigames had some timing requirements like lining the knife up properly or needing to spin the pestle fast enough to get a reaction, but that would have A) be kinda overscoping a jam and B) might cause more issues with communicating how the game works, so I dunno.

It took me a reeeally long time to figure out that the big guy guarding the meat wanted my stone money. I actually already closed the game and deemed it unplayable, but then I kind of got angry with myself by being too stupid for stone age trading and started it again!
I liked the mechanics, but I think the optics of the ingredients (and the above mentioned stone) were a bit misleading. I have no idea what that one yellow thing next to the eggs was supposed to be, and overall the potatos, that thing and the eggs looked too similar. Once I figured out how to play, I was able to beat the game easily. Albeit the walking animation was great to watch, I would have wished for new customers to appear a biiiit faster (they were probably just exhausted from all that hunting and gathering..)
My first two customers appeared to be unstatisfied with my meal quality, they simply collapsed and vanished - I am not sure if that was a bug or if I poisened them or something?

Overall, I liked the idea and the design, the music was fun and fit the derpy movements and style of the cavemen. With a bit of polishing and some fine tuning in the level of stress (multiple customers, customers that get angry when you don't hurry up, ect..), I think this could be a great little casual game :)

Unfortunately I think this game was just trying to be something a little bit too complex; too many possible types of interaction (with not enough guidance/feedback for each). Lots of signs telling you what to do with what, but I was moving things around, putting them on boards etc. pressing E all over the place and none of the food appeared to be processing. 

Games are fractal. Good quality games are made up of tiny good quality minigames. I think a good reference point for the type of thing you were trying to do "i.e. Overcooked but first person" would have been something like the potion brewing minigame in Kingdom Come Deliverance 2; a few different things to do, but without all the dead time wandering around between stations, and too many operations which don't have any animation/feedback etc.
