Congrats on your game!
Super clean style. I really enjoyed the almost toy-like paper quality of the art. The premise is solid, I can see lots of room in this system to flesh out a game.
The controls were a bit frustrating. I found that I needed to move things very slowly and precisely or quickly lose control and have to completely stop to regain control. This made the game feel super slow-paced for what felt like it should have been a more simple task. It's tough to get physics controls to feel good, especially with a limited timeframe, and I think this just needed more time and playtesting. I couldn't get through the second stage without getting frustrated when my roof piece knocked over a wall. I thought I was setting it down carefully, but the need to hold space to keep the claw open was unintuitive and I always ended up knocking pieces out of true. In this case, setting me back way more than I was willing to redo.
A tad frustrating, but an overall cool project with a take on the theme I haven't seen much of. And you made it in 96 hours, which is a feat by itself. Congrats on submitting! And keep making games! :)
