Thanks for playing and for such a detailed review!
For the art, the concept was in fact disney/games for girls/cartoon network style flash games from the early 2000s, so kudos for picking that up!! Also glad to hear the music synced well for you, because we had some issues on some player's devices with that.
Also thanks for the grandma mental image, haha. That's also an interesting point - I think as a dev I am used to touch typing so multiple keys are not a big deal. Tbh it's interesting to see how much I underestimated how difficult it would be for people (^-^;
In terms of the limitation, that's where the "switch screens to make the burgers" comes in. The idea is you can get the highest score by making burgers whenever you run out of customers, and then when you "look back" more customers have arrived who you can then sell said burgers too. I thought about adding more to this like customers having a time limit so if you took too long making burgers they would disappear as well (more "changing while you look away") but thought this might be too hard - and thank god I didn't lol.
Cheers again and congrats on making $20 :) I think after this jam I'll add in a bit more tutorial / controls build-up so that it's more playable in the off-chance anyone ever stumbles upon it again xD
