I find the 3D excellent. I learned too late that movement was an option.
I'm not sure about theme or originality but does it matter when the game is fun ?
Yeah. My original idea was that you would have limited number of balls that you would have to pick up from corners and they would return back to you after rolling off edge (like in real bouling) and they could be individually "evolved" into different types of balls. But I quickly realised I won't have time for any of that :(
Maybe after the Jam ends.
