This was a lot of fun. I remember Zachtronics including a minigame similar to this in Last Call BBS, but that was in 2D and a lot less entertaining. It would be cool to see features like posing the models after they're finished, or being able to connect parts to the wrong places (accidentally or on purpose). I could see myself playing that for hours lol. Like working on your build in Armored Core but only worrying about how fresh it looks instead of the stats

Do you plan to keep working on it after the jam? Either way, you've definitely earned a follow.
Also, did you do all the models yourself, or use an asset pack from somewhere? I tried doing some mech modeling a bit ago and came up with some decent stuff, but it took a while to figure out how to create interesting shapes while maintaining planar face
