Not to be mean but if you don't know how to do an IF/THEN statement then your "basic knowledge" doesn't sound like very much. Check out TDKs tutorials first:
Part 1 will teach you about storing values (like score and a goal) in variables and/or arrays and it will teach you about IF/THEN statements.
Part 2 will teach you about loops so you can have multiple objects falling at the same time.
Part 3 will teach you about screen coordinates so you know where everything is going to go and how to make things "fall" from the top of the screen.
Part 4 will teach you about reading/writing to files and how to make high score tables.
Part 8 will teach you about timers and how to calculate them for your time display.
Once you start learning the above I'll teach you how to load images and work with sprites. Post in this thread any time you're confused about TDKs tutorials or about your own code. We will all do our best to help you through this class.
