I really had a blast with this! Even in prototype form, there's a lot of potential here.
One thing I noticed - whenever I tried to microwave anything, it was an instant game over, even when it was the correct reagent in that run. Not sure if that got fixed in the update, but if not, I felt I'd better call it out.
The other thing I wanted to mention was that it seems like this game might very easily lend itself to unwinnability without considerable effort on your part. For example, in my last run, there was a reagent on top of the wall cabinets - I noticed it before I was quite too short to get up there, but if I hadn't, the run would've been cooked and I'm not sure I would've known it - that was the first time I'd seen anything up there! That's not something it seems possible to handle perfectly in all cases - I'm not even sure that kind of complex path prediction is possible, and I'm almost certain it can't be done in less than exponential time, which would have to make it a non-starter for a game that needs to run at or above 30fps. I'm not really sure what to recommend! But, again, I felt I'd better mention it.
Other than that, I wouldn't change a thing, and even just playing it a little while I had a lot of fun! It felt like a real challenge, and the need to act quickly and correctly under pressure makes it exciting. Thanks for making it, and I'm looking forward to seeing it more fleshed out!
