If you are able to play the game just fine, please disregard. ːsteamhappyː
For those who have trouble opening the game, please go into the installation directory (right-click the game in your Steam library > Properties > Local Files tab > Browse Local Files) and run the runtime.exe. Orake Classic runs on a very old engine, so the runtime MUST be installed in order to play the game. It installs various discontinued dll's and ocx files onto your system.
We are looking in to upgrading the engine. Also, the sequel will run on a different engine (Unity), so this won't be a problem in our future games!
