Rule #1: Never use Cset 2, 3 or 4 for sprites. These are for combos- the colors are level specific and tend to change the most. (more than Cset 9 which is also level specific.) Please use Csets 0,1,and 5-11. You can change your Cset with + and - for those of you that don't know.
Rule #2: Unless you are using the classic set, (or are making a background) Don't make flat-shaded tiles. Use at least two shades.
Rule #3: Don't make a tile for something that isn't implemented. *Obsolete with scripting... just make sure it's possible*
Rule #4: This was apparently a big one. Make sure it hasn't already been submitted if it is a rip.
Rule #5: Show it to one or two other people first. If it does not appeal to them, edit it.
Rule #6: If it is animated, make sure it looks and flows right. Users and players don't like choppy animations.
Rule #7: You should have at least one screenshot/the tiles themselves. Nobody will want it if you don't have screenies.
Rule #8: This should be obvious, but I'm saying this anyway. Make sure it looks how it should. If it is supposed to be a crystal, It should look like a crystal!!!!!
Rule #9: Arrange your tiles in the easiest way possible to make it more convenient for the user.
Rule #10: With custom tiles, use good or accurate colors.
Rule #11: Make sure it works in ZC. Test it with the grabber. (I've made this mistake before, even though I fixed it.)
Rule #12: Don't mix sprites with other sprites that you aren't submitting. Have just the sprites that you are intending to submit.
If you comply to all of these rules, then your submissions won't be rejected!
It may be common sense, but it's a good reference if you don't understand one of these concepts.
Anyone that would like to add to this may.
