Needs some polishing, but I had a good time! :D 

Interesting and creative idea but I think the execution needs some work
The simplest change I would make that I can see improve this is to make a point-and-click type game with a high-angle camera so you can get a view of the whole plane and the objects in it and manipulate all the objects in the field by simply dragging and rotating them and putting them where you want. All the mechanics can stay the same
nice idea and good job!!!

Nice little challenge, not too long for a Jam.
I was able to do it with 3 Objects, but it was a bit tricky to get the Container on its thin side with the limited rotation :)

Cool open ended puzzle! The assortment of odd shapes to reach the goal was great, and the models are very clean. I won when I precariously balanced the ship on an odd bit of the race car and it held for just long enough.

A couple minor complains though:

• A restart button with no 'Are you sure?' of any kind bit me a couple times when my mind told me 'Press R to Rotate' even though that's very much not the rotate key.
• Objects casting shadow directly below them would have been extremely helpful

Really enjoyable, lots of room to explore quirky ways of reaching the goal!

UI can seem a tad full at times, but not too distracting.

Controls were easy enough to learn, though rotating objects could be a little tricky.

Twas' good fun, very well done!
