This is an super impressive game with just 3 days of work. The SFX/BGM and art are professional levels, and I really love this idea of sticking to and pulling yourself up to objects in the environment. But the delay that you've implemented after sticking to something makes the cursor appear so that nothing is grabbable. That's probably intentional, since the player isn't able to grab anything during that time.
But it's already hard enough to tell what is/isn't intractable in the environment, plus dealing with the constant falling, that you can't plan your next course of action; it turns into frantic clicking and internal praying. I would've loved a 3rd cursor to show when something is grabbable but the stick option is on cooldown, or some sort of effect on the white cursor to show it's on cooldown but lets you plan where you wanna stick next.
Nevertheless, I'm giving this game high votes. And I know other people will love it for what it is: a well-constructed, challenging, and overall impressive game. 😊
