This is actually fairly close to perfect for me. Infinifactory being one of my favorite game all time, it's really hard to not fawn over this and leave a trail of saliva on the floor.
Presentation is excellent, I love the game, although camera rotation would have been welcome, especially to place the beam downward, and shift key acts real weird. And it's just a perfect for the theme. I'm just going to say that it's not very original, being very close to a clone of Infinifactory.
I encountered a bug seemingly due to wielding + moving upward a block, which makes handling moving stuff upward very difficult.
The game lifespan is over 2 hours, this is amazing for a jam game.
