okk, so, I added music and sfx OMG DIGGING IS SO SATISFYING NOWW (sorry caps lock) also building cost money (I had to do it sometime) but, the dinosaur statues generate money. (you have to exit build mode to collect money) also, dinosaur levels work :)
i either wrote the music, or got sounds from public domain things, or free sounds from projects. (I'll find them later and give them a shout-out)
