Suggestions On My Project?

Pokemon Atomic Engine



So Im making a game for my AP Comp Sci class and Im a Sophomore in High school and turning 16 in 1 week. I have been using C++ Since I was 12 and Game maker is so elementary.... So Im making a Pokemon game, but not the tradtional pokemon game. Kind of like the Pokemon mystery dungeon games. But more like a shooting game.

-2d Overhead View
-Programmed in C++
-Using the SDL API
-Using Kanto Pokemon Only (That can change)
-Using the Heart Gold/ Soul Silver pokemon sprites (the one following the trainer)
-Making a Map Editor
-LUA for scripting
-Making a Custom Particle Engine for attacks like Flame Thrower

Im just making the game engine and map editor first and then using those to make the actual game. I just need suggestions on what Im missing out on. No suggestions on the story yet, just the game play and engine

Keep in mind, its all from SCRATCH, except the sprites and music (Im no artist or sound maker person)

And dont think its not going to get finished, Im doing it for a grade, LOL It has to get finished.
