I have no one to play this game with, so controlling both characters simultaneously makes my brain detonate.

I think the other comments say everything there is to be said about the string. I found it hilarious how, in level 5, both characters ramming themselves into the wall will cause the string to elongate out of the screen for kilometres. I was hoping I would have a giga slingshot when releasing the keys, but instead it just made it visually freak out.

This is secretly a rage game. The levels are very much on the hard side considering the unpredictability of the core mechanic and the absence of checkpoints.

I however think the idea is genius, I have not seen a game like this before. I think a version of this game where the string follows physics more accurately and does not go through walls would sell like little hot breads on the Steam market. Not to mention the art's minimalism yet consistency is both cute and immaculate.

Love the art style and mechanics design. I'm sure if given more time polishing the programming, it will beat Fire boy and Ice girl!  

I see the potential in the game mechanics, however I found the levels pretty difficult and the string mechanic to be a bit frustrating to use because it wasn't dragging along the characters the way I expected it to.

Especially the first level, I find it a bit too difficult for a first level. A lot of the jumps in the first level make you rely on coyote time for the cat character which imo shouldn't be a thing in the first level. The first level should be introducing you to the basics of the movement and the mechanics. While you did do that, I think it shouldn't be this difficult. Also, in the first level after you pass the first 2 switches, you can get stuck if the bunny make the jump (unless you do a double jump and hug the wall to touch the edge tile so it resets your jump).

Also, a lot of the buttons were located at pretty frustrating places (Beginning of second level for example). It felt as though you really had to be precise with the placement of each character so you can activate both buttons at the same time. You should give some leeway.

I do really love the ideas you had for some of the levels (level 3 especially), but I think you should tone down the difficulty a little bit.

The art and sound design is really awesome I really enjoyed looking at each level!

Otherwise, I really like the gameplay idea and I do see the potential in it with some tweaking to the difficulty, string physics, and movement. Great job!!

The string is a really neat idea, but in practice it makes both characters unpleasant to control, because they're both weighed down by each other. I tried all levels and couldn't finish any of them (except 5 lol) because of some frustration with the physics.

The fact that the chatacters can't interact with things of their own color is very interesting, and I wish it was implemented into more of the puzzles.

I haven't encountered any puzzles that required the swap mechanic, so maybe that could have been expanded upon as well.

A minor problem I've noticed is that a lot of the puzzles required the rabbit to be on the left and the cat to be on the right. Given the control scheme, it would have been nicer for it to be the other way around to make it less confusing for solo players.

So in summary, this game has great ideas, and less than ideal execution in my opinion. Amazing job nonetheless!

You won't get over Fireboy & Watergirl, but it's close.
