First of all, I love how visually cohesive everything is, and the art style and the palette is really cute!
The game itself is veeery addicting, I need to force myself to stop playing! Really like the feedbacks it gives, like that fading white stars, and the sounds too! You can definitely sell this on mobile platform! 5 stars from me!

It's really simple but I think that's in a good way. I like the art style and sound effects. I don't think it has much replay value though. After a minute or two I already know everything about what this game is about.

The game looks really clean and nice, I love that. Also, IDK how a game like this made me play for so long xd, I guess it's just that relaxing, I do like the mobile game vibe it has. I got to level 19 I think, and it took me a while to realize you could buy new skin, when I did, I got myself a nice cat.

 I would like a challenge mode, like you have to avoid hitting bombs or something, maybe make the playfield bigger so you have more level design possibilities. Also, IDK how much this can mess up the balance of the game, but I found myself trying to use variable jumps like most platformer have, but this game doesn't, I know you can pick up speed to jump higher, but I would like to also tap or hold down to button to vary to jump height even more and have more precision. 

Then again, I'm not an expert player and I didn't understand how to optimize my jumps to get more ''points''.

First, I must commend you on putting in such a large amount of polish. I can tell despite the simplicity of the game a lot of work has been done to make it feel fantastic. The graphics look great, the sound effects and feedback are incredible.

Best of all, is the insanely addictive gameplay loop. It gives me the same feeling as something like peggle or breakout. After a little bit it did start to feel pretty repetitive though. I think with just a couple things though you could have had me playing for hours!

1st, I think you need to work on adding some new powerups and unique mechanics. You could explore things like breaking up the players circle into multiple smaller ones, adding a bounce, changing movement speed, jump height, gravity, etc.

And I also think you should add some kind of progression or goal. Right now it feels like I have no reason to keep playing past the simple gameplay loop. As good as it is, it wont keep players around for long enough. I would look at how games like Peggle solve this, and try adding some things like increasing difficulty / complexity as you level up. You could also try adding some kind of score system, but I think the problem now is there is no way to "lose" which trivializes the score in a way.

Fun game. Good level of polish on this! Really liked the simplicity, with the one button control. I felt the game became a little repetitive after a while. Introducing more star types would be nice. Bombs to avoid might keep the players on their toes, with some lives. Overall this is a good base to build on. All the best!

Indeed the game loop is quite clever, simple and addictive like you said, you can easily spend a lot of time with this, but I do miss a couple of things that I think woul make this even more addictive an add more depth ... 

since it is a small interface I keep thinking this was meant for mobile and in the mobile this could make good use of accelerometer in clever ways (well, you might have already thought about it cause it was the first thing that crossed my mind on my first minute of gameplay) ... like, I want to have more ways to control the movement of the ball, so I feel there is depth to be explored and expertise to be earned ... like games that are easy to get started an feel the addictiveness, but can also offer some depth for those that want to be the best at it. I do imagine people moving their mobiles like crazy to get high scores though lol. 

Great concept!

The graphic is so lovely!
