Whoa, Just when I decided that my modded version of Life2x (which has a doubled field size and some other stuff, but also has a naggy crashy bug that crashes the game after a lot of generations) wasn't good enough to get released, and just when I decided to make my own version of Life for the GP2x, you show up with this version!
And I must say that I pretty much like it, however, there are a few things I would think would make it even better.
1) Allow the user to get a bit more speed out of the generations. It feels kind of slow now (6 generations a second, or so?)
2) Allow the user to turn on/off the grid, and then make sure that the grid is filled with a cell's color, too (I just don't like seeing a line between two black cells. :/). Shouldn't be too hard when you make it so that if the grid is ACTIVE, it is being "drawn" on the top and left sides of a cell. So this way you could have it active (and get a 5x5 cell) or nonactive (and you'd get a 6x6 cell)
3) Allow for more zoom modes. I'd love to see a 1:1 zoom mode where 1 pixel equals 1 cell.
4) When the user holds Y and uses the joystick, move the screen instead of the cursor.
5) Allow the current generation number to be displayed on the top statusline. Could also be made so you can switch between generation only, active cells only (like it is now: "25/75000") and both (so you would get something like "25 - 100" which means 25 alive cells, 100 generations).
6) (this is not really that much needed) allow popular cell construction files of other Windows/Linux software to be opened and placed.
7) Move the L button's action (the help thing) to a subsection of the R button (options) and use the L button for something else, such as file actions.
That's it, I think..
Even though it's got a few things I don't really like, it's still an awesome Life sim on the GP2x.
