Hi there mochaa_teddi! I'm sorry that the game doesn't work for you. To try and fix this, we will need some more information.
Please send us an email at support@tripletopping.com with the log and save files attached. You can find the files by opening windows explorer and pasting this path: "%appdata%\..\LocalLow\Triple Topping\Dead Pets Demo" without the quotes. Please include all files in that folder.
Thanks, Jonathan @ programmer at TripleTopping
