I think it is a really interesting idea!
If I were to make one change, I would change the scaling buttons to keyboard keys, as the coloured blocks could be hard to hit at certain scales

Some instructions that this was a platformer would be handy.

There were a couple of small issues with the control surfaces also scaling with the blocks (maybe they were children of the scaled node?), and blocks also not returning to their original location when the opposite scaling option was used.

However, cool idea and good job.

I think this idea is actually really cool!

Great concept and on theme!
