good game
Very good game, puzzling puzzles that are fun to solve.
Here's one place where there's a simpler solution:
on level 30, you can put these components in the following places:
fans at: I2, F3, B6, & G10
steam detectors at: H3, & E5
batteries at: H2, D3
hamster at: C10
cannon at: H10
you don't need a block or a puller bot at all.
