I got one with 3 bones and 2 muscles to go as fast as 30 m/s, less than 4.5 kg, on gen 1-2.
Edit: Gen duration 60s
Edit2: Top speed 32.05 m/s, hit it on gen 3
Cool game, pretty funny. Fun Fact: the dollop of green mush in most American sushi boxes and restaurants is actually not wasabi, its mainly green dye and horseradish. Real wasabi is quite expensive, at upwards of $200/kg.
Cool simulator, hard. I solved most of it but I got stuck on the last two sides.
Cool game.
