Qt-based 2d Match-Three Game
JAG is an arcade-puzzle 2D game which runs on Linux and Windows. The aim of JAG is to break all of the target pieces on each level, and to do this before the time runs out. Keep doing this until you have beaten the last level and won the game. Move game pieces using mouse into matches of 3 or more in a straight line horizontally or vertically. Doing this on top of the target cells will break them. The faster targets are removed, the bigger is score. Some pieces are blocked. Before removing such ones, blocks should be destroyed. By breaking pieces and targets, you're earning score which can be spent for applying a special tool. Tools make the life easier as they're mostly intended for breaking several pieces at a time, including blocks and targets. By breaking pieces of the same type, you're also increasing bonus counters. If you will collect 500 and more items, you can remove all the same items from the field.
