I love the low poly crystal. Very enjoyable.

fun to play

That's a lot of ambition! The graphics are great, but I kept doing the wrong thing when the ball kept talking about equal and opposite reactions. I also felt like I couldn't control my character through the balls very well in the game.

interesting concept

Cool game, but i think the controls are a bit hard

Very interesting, a bit difficult to grasp without doing the tutorials first though. Nonetheless, it's enjoyable.

Love it, the camera could be from a higher position, so you do not creep around, but it is really nice. Love the intro voice :) Good Job!

Interesting concept, and nice work spending some time putting a tutorial with audio in the game! It seems to suffer from a few physics bugs though, as I managed to lose quite a few balls through the walls.

Did you recorded all audio effects using your voice? Ahahah, great! We also thought about it, but then we went for some 8bit sounds instead :)

Concept and gameplay is interested, I really appreciated the tutorial too. Maybe it's a little too easy to get stuck on walls or because you make a sphere fall down when it is not intended (see level 1).

The art style is awesome, as it is the audio on the tutorial. The controls are too difficult (maybe 'cause I'm using a touchpad), and I couldn't beat the first level. :(
The tutorial could have some subtitles too, I'm not a native English speaker, so I couldn't figure out what I should do.
The mechanics are nice, and I loved the Portal-style humor. Nice job! :)

The core idea is great but the engine needs more tweaking. The ball of the first levels are falling off the making the level impossible to finish. Then I was stuck in the grey platform just near the teleporter.
