Very good game with a lot of potential design-wise! The earlier levels can be a bit uninteresting since they only have a few types of components, but later levels have a really nice push-and-pull play space where you get to decide which piece you get to assemble; do you leave out the piece that requires sautering that's first in the assembly line or do you do the piece that only has bolts to tighten? Very good job, has a lot of potential.
