Tasked with a varsity assignment to combine tower defence with another game; as the name suggests, I chose Tetris. The player uses their keyboard to play a game of Tetris on the right hand side of the screen, whilst using their mouse to place and upgrade towers to defend against the incoming waves of enemies. Every time a Tetris block settles, a tower of that shape could be placed on the map. And every time a line of blocks is cleared, you are awarded points to spend upgrading towers. I made this game because the fun part of tower defence games has always been designing clever mazes. I thought a good way to maximise maze designing was to force players to constantly be using randomly shaped towers and placing them in an irregular twisty corridor. Turns out having them also play Tetris at the same time, was obviously a bad idea.
