This image shows the gameplay of our completed casual tile swamping game called TumbleGonk. This is a continuation of a concept game that was first show on the IOTD a few years ago as a Java based game called Blackhole.

A custom graph data structure is used that allows for the polar based tile layout shown in the image. The code also features a basic GUI API used to display the buttons shown in the image. Bitmap font rendering is used to display all text in the game. The whole game engine is designed to be as resolution independent as possible using the hardware accelerated scaling of SDL2.

The original goal of the project was to be a commercial game that would be sold on services such as Steam, but for various reasons this never happened. Now there is an Indiegogo.com campaign to try and raise the funds ($850) required to release the game code and art under an open source license.

You can find a fully playable windows version of this game at the indiegogo campaign gallery http://igg.me/p/226582?a=1223497
