Note: I played Android version.

Really loved the sounds and music from the moment I opened the game, It is chill and fits graphics pretty well. On a phone it felt that I wanted a bit more sensitivity for controls, as my finger would often not have enough space on the screen to slide, however I got used to it, so I guess it's fine. My favorite part was how you introduced new mechanics in a safe environment, and then created a challenge with them a bit later. It's surprising how many new mechanics you can introduce so intuitively.

I also played your game. Nice idea. I had a problem to drag the mouse as much as I wanted when the pointer was off the screen.

This game has a lot of potential, but the controls are annoying and unintuitive. I also think that the materials have too high a friction value which stops the ball from moving sideways without going in the air.

Really like the aesthetics and controls are kinda similar to what I was going for too. The puzzles themselves are really nice too. :) One suggestion, you can show where the user started clicking/dragging because it can be a bit confusing to orient. 

Cool entry. Unfortunately the browser version does not work quite well. But nevertheless I had a lot of fun playing the game. :)
