I like this game a lot! The visual style is fantastic, and I feel like you've got a great start here on a good puzzle game!
I've seen a very similar idea quite a few times so far in the jam, however yours is the first I've seen that allows you to resize and object while the player is on top of it. I didn't try that for a bit because I assumed it wouldn't work but had the biggest smile when it did. I think that mechanically sets you apart nicely. I'm sure that's tough to debug. It's also cool you can change sizes while holding an object!
I think one small thing that would improve this game is a tiny UI element that says something like 'Press F to interact' on a switch. I walked up to the first one and forgot what the bind was.
Awesome showing!
