hi, wanted to know if you can do something like that in blender, and as ¿?
Yes, it would require Python knowledge though. And if you wanted people to play it like a flash game, you would need Burster.
This isn’t a simple project, but yes, it’s possible.
Of Curse you can. But the Question »how« (not as) is more than vague.
EDIT: RossBlenderArt’s Game »Grid« works pretty similar. You may take a Look at it.
