Looks good but I really don't like playing skill games with a keyboard, add controller support and it could be good.

Most of the game is in english but also get what looks like russian text in some parts of the game.

How is the co-op going to work? Is it going to be a special set of levels meant to be solved by 2 players? Can you give a rough idea of how big that content is compared to single player?

Such as why all the balls? And which one is me, and what am I supposed to do with all the others? I presume this a meant to be the easiest concept in the world, but I don't even know why getting to the end of the first level (?, the up arrow ?) served no apparent purpose. I've played hundreds of games, and generally being ABLE to access the end either means you're finished, or something fairly obvious was missed. Please, try to forgive my ignorance, and try to respect my (now) transparent vulnerability....

This looks very very much like the game Ballance from a few years ago. The gameplay, models, textures, etc... Is it some kind of sequel?
