Very interesting puzzles! You should probably add more checkpoints because it's a little frustrating not to be able to restart the very thing I was doing!

I stopped at the barrier protecting the button at the ceiling. I tried some kind of catapult-like shape but it wasn't reliable enough!

Very addictive, though, I got hooked quickly!

Really neat idea! I got stuck at the puzzle where you have to activate a button on the ceiling that's just past a barrier... I wanted to make a ramp-thing and launch an object into it, but it was cumbersome to try something and then have to restart from the checkpoint and get back to the room to try something else, so I ended up quitting.

But the amount I experienced was really pleasant! I especially loved the puzzle where the button was on the ceiling, and I drew something that hooked onto both the circle in the room *and* the ceiling the button was attached to to keep it pressed while also ensuring the drawn object didn't fall.

Smart and interesting puzzles ! 
Moving around is a bit janky but I like the different ideas you came up with for puzzles and the way we interact with objects weight

Lots of interesting puzzle potential with this

Puzzles are quite enjoyable! I like that weight is stacked, meaning you can draw small but heavy objects.

Maybe you could change the color of the drawn object depending on the weight (e.g. blue -> red).

Just needs some polish, but totally understandable since it's for a jam :)

Wow, original =) I like it

Awesome entry! I found some small bugs and didn't read description for first :D Was reloading page multiple time and then read that to restart I can press R :D If you draw line slowly, it will take more ink. For example I couldn draw first bridge 3-5 times because I ran out of ink. And then I tried to draw it fast and it helped!
