Hey, I have a solution to your problem here. It's really simple, you just need to find the savegame location and edit the save file like a normal text.
It's either in your Steam folder (*\Steam\userdata\*\748890\remote) or in "C:\Users\*\AppData\Roaming\*\remote" folder, go into the Roaming folder and search for the Steam App ID"748890". The save file looks like "storePSrebelsPSstate". You can use this method to cheat any game based on this engine. To learn the Steam App ID just go the store page of the game (e.g. http://store.steampowered.com/app/800560/The_Great_Tournament_2/).
Have fun! I also can recommend you to try The Choice of Robots and The Great Tournament 1/2 (these are some of the best games of this kind), if you haven't already.
