I love the core idea. The building process was really fiddly though, often the parts would just fly out when I tried grabbing them, requiring me to reset the building entirely. Which got worse the more parts I had access to.
Also there is little feedback to what is actually happening during the game phase, which makes it hard to plan what to account for.
But it was really fun building something, seeing where it breaks and adjusting the next design.
Overall, a fun entry, I liked it! :)
