Once you've realize the game you want to make.. focus on it!

Next problem you have is the implementation of the game. Right?
Here's some tips:
1. try to search in AUM for that specific problem
2. try to search in the forum for that specific problem
3. lastly, post in the forum your specific problem, in that case, other users can respond/understand it well.
4. don't give up & be patient! sometimes, there would be no people can help you... but just yourself! laugh

Btw, this is Lite-C programming thread.. for your query, I assume it's a 2D game, try to look at the AUM81 (or search it)

Have fun! Cheers! smile
