Been a while since I speedrunned Tetrobot and Co. but with a bit of training I was able to do sub 3h (as I thought) and even sub 2h30. Huge loss of time at Big Mama, totally forgot how to do the last puzzle, and a small loss of time at Big Mamamia thanks to a bug that slowed me down. Could still improve the run, I think I could do 2h20
