About this game

As part of a university project, this game was originally developed for an Arduino Mega with a 320x480 TFT display communicating via SPI. This game pushed the limited graphical capability of the slow transfer speeds by only drawing pixels when necessary. For this to work, every time a sprite is drawn it first needs to be "cleaned up" using a function that draws background pixels over the old position. This achieved ~20FPS on a setup that normally would take 3+ seconds to fill the entire screen.

After completing the project, we decided to port the game to PC, using the SDL2 graphics library. A simple wrapper to translate TFT_espi calls to SDL2 calls was put in place and most of the code was made to work with plain C++ as opposed to Arduino C++.

Glup's Quest takes approximately 5 minutes to complete and has 4 worlds with 5 levels each, plus an extra challenge of four extra difficult levels.
