I think the music in this game is one of its best elements. I downladed it to iTunes and I listen to it whenever I need to relax.
To get back on topic: I think it would be nice to have themed releases. With the Nostalgia tree there is not a whole lot can be done but there could be a Winter / Summer / Seasonal / Toys / Food etc releases. Maybe cheaper, maybe not - depends on the amount of content. I think there is a danger that by having too many objects in a game it becomes too much and can detract from the game. It could make the game seem more of a task. And by doing themed releases you broaden the appeal.
Themed releases and with themed wood shapes would be a great addition. A kiddie tree with easy shapes, a sports tree, a vehicle tree, maybe even a tree with iPhone characters (Toy Bot, pygmy).
We wouldn't make extra trees unless we felt the theme was solid for 25 objects. But manipulating parts of objects is not a feature that will be in Zen Bound, that kind of interaction belongs in a separate game.
Depending on what the meat of the problems, $1 for 1 tree is very generous price, I think. You could also include extra audio track, which should match the theme of the tree (under zen world, of course). Serious puzzle fans, for puzzles like from Nikoli, pays for "problems." There are so many Sudoku programs and many (dumb) of them generate problems on the fly with poor random algorithms (or pre-generated, but they're no different). Puzzle experts like Nikoli doesn't do this way; problems are not randomly generated but carefully "designed" and only selected ones are released. The "theme" of a problem considers visual presentation of the problem and target difficulty for it takes selected level of known heuristics and techniques. Good problems can make you think about what's on the mind of problem creater for that problem when he creates it. Huge difference from randomly generated stupid problems. Hundreds of boring, "same" different problems wouldn't worth one well-thought problem in value. So many third party Sudoku programs are proud of this kind of thuoudsands of, or infinty number (dynamically generated) of boring problems. The puzzle isn't a logical game anymore; it's then more like Tetris or Bejweled. Zen bound isn't a deep-thinking logical puzzle type but I think it has an essence of such puzzle ...problem oriented. So I'm all for creating and charging extra problem packs as long as problems are not just simply collection of "another shapes" and could give something more. Otherwise providing only large number of basically the same problems isn't too appealing. Well, maybe I'm asking too much
Lol, j/k. That would ruin the whole zen experience. I'm all in though for additional themed packs as some suggested.
