Some really nice puzzle design! I think you all have done a really nice job of taking some simple mechanics and producing some interesting puzzles from this simplicity. I genuinely had fun playing this. I liked when the levels started having all the conveyors, I thought that started to get quite interesting.
The early levels do a good job of teaching you the mechanics. Controls are simple and intuitive. Music, SFX, and atmosphere are all consistent and work with each other. And the homage at the end is fun.
I'm honestly having trouble coming up with constructive criticism - most suggestions I can think of are just like adding more worldbuilding, more puzzles, leaderboard, multiplayer...just adding more features haha. Really solid job.
