A lot of games have PC or the console level graphics and the thing is that they tend to drain the graphics. I am sure you can find it if you see it there.
True quality suffers when we cut the cost and try to make things cheap. I have noticed that huwei is moderately priced and also good for overall performance.
Puzzle games requires certain level of patience. And based on only that we could do anything good. I know a lot of folks who don't get much into puzzles.
if you try to make it more or realistic like say with cryengine or any other 3D that would suck in a lot of your funds for all the development. for reducing price childish 2D sounds better.
