Clever game once I got the hang of it. I didn't realize that there was a path for the smiley face to be walked.
Well done to implemented the limited space but it would more suite a ' you control the level and not the player '.
So in fact it is a very well made entry for multiple themes :)
I might get back to level 8 since that is where I struggle most!

A great game and a fun challenge! It would be better if it automatically went onto the next level when you completed one, but that's a minor complaint since you can easily change it yourself.

Super neat game! I loved the dynamic music system (and smiley faces), it really added to the experience. Only things I thought were missing were an explanation of the scoring system, and some way to know the level I'm currently on.

This is clever! It’s pretty hard—I can’t beat level 4 for the life of me, I’m too slow. Very original mechanic though, and the faces the circle makes add a lot of character to it. Nice work.

Really like this! Manipulating the geometry is so fun. And the neat graphics is also satisfactory to see. :D

The head of the circle is incredible! A really interesting game to play and not so obvious, for a puzzle game with a few more levels it could be great!

Really nice idea that was easy to grasp but VERY hard to master. I'm not really up to the challenge and get bored a bit too easily. So I would've liked the game to start off a little easier after level 1.

Love the faces on the little circle guy. I think this is a really strong idea that could translate well to mobile touch screens! I do wish the vertices moved a little faster though

That got quite frantic :D Unique gameplay and great difficulty ramping, it gets surprisingly difficult to drag around multiple points at the same time. The faces were a fun touch, I feel like I made the same ones while playing :P

The game is really fun, I feel like it's gonna be great on mobile device

A very clever idea for a game, and the execution is pretty damn good as well... But it has some very frustrating issues with controls.

After playing through it all I'm still not sure if I was more helped or hampered by the automatic selection of the nearest node. It was very difficult at times - especially when two nodes were pretty close together - to figure out in a blink of an eye which node will be moved, and quite often it wasn't the one I wanted and I failed the level. Though that probably is something I'd get more used to with time, as after a while it became a bit easier and the failures happened less often.

Bigger issue is that it is played on a canvas in a browser window with unrestricted mouse movement. For more precise control I dragged as far away from the node as possible, but that often meant my mouse cursor left the canvas while dragging. If I released the mouse button while it was away from the canvas, it acted unpredictably - i.e. it didn't detect the mouse-up event, and the node was still dragged. Best way to handle that would be to restrict mouse movement to the canvas using Pointer Lock API, but that would require at minimum drawing the cursor on the canvas yourself.

Without that, after about 30-40 attempts to complete the final level, I've worked around the issue by forcing the canvas into fullscreen mode, and that finally let me complete the game:

The idea is simple, but very effective. Thanks to the area of the polygon remaining constant as its shape changes, you get a lot of strategic choices, like whether it is better to drag the vertices directly on the way of the ball or to push the vertices in the back to move the entire polygon forward. And given the fact you've got to think quickly, you get a pretty hectic gameplay that gives a lot of satisfaction when you complete a level.

I really loved that the music changed based on the distance to the nearest point on the edge. Just the changing faces on the ball would be enough feedback, but the music getting more intense really built up the pressure.

Lots of fun and an interesting take on the theme. The levels had a nice variety on the core mechanic.

Maybe it was my mouse but I just couldn't move the points fast enough and the ball moves SO FAST. I got stuck on level 3. Very cool, very INNOVATIVE game design though!!!

really fun game. The scoring system was a bit hard to understand though, and I think a next level button would've been really nice instead of it immediately restarting the level on clicking. Beyond that very enjoyable and I loved the chagne in expression of the circle.

A very creative idea for the theme! Good work!

Great rage game. For me, Level 4 was quite hard, level 5 much easier, level 6 in-between. Level 7 a pure IQ test that I failed. Level 8, I consider reaching the first line at the top a success.

Well rounded game, it is clever in particular that the ball has character. It could be a great teaching tool to help kids learn to hate geometry.
