Here is the game's Steam store page: http://store.steampowered.com/app/42140/

To quote the description on that page:
Hamilton's Great Adventure puts your problem solving and timing skills to the test. Outsmart the enemies, rush through the levels and collect all the bling to ensure your place on the leaderboards.
In single player, switch between Hamilton and Sasha the bird to get through more than 60 challenging levels, or play the game in offline co-op mode and control one character each! The game supports both keyboard/mouse and game pads.
The increasing difficulty will keep even the most seasoned gamers on their toes and only the players with Mad Skillz will make it to the end. Will you be one of the select few in the world to complete the Toader level 100%?

IMPORTANT: The game only works on Windows Vista and Windows 7. Windows XP is not supported.

Obviously you need a Steam account to play. To activate Steam Keys, open the Steam application window, click "ADD A GAME...", then select "Activate a Product on Steam...".
