Yeah, sound is a big hole in my gamedev arsenal u.u I'm working on it but I'm so bad at it, nothing sounds right.
How you get ingredients was a big design decision. i wanted the gameplay to be about making the most of what you got, and to align with the "scarcity" theme. You get them randomly when enemies die, and sometimes it's too punishing.
I know that with some luck and some knowledge you can reach the 150ish points.
I'm glad you played and liked it! :D
