Quick Draw McGraw (UK) (1990) - Amstrad CPC - Action, Western

Quick Draw McGraw is a side-view horizontal scrolling game based on the Hanna Barbera cartoon character where the screen scrolls constantly from right to left. You control Quick Draw whose mission is to protect various trains from being attacked and robbed by various characters, by running along the top or by the side of the carriages of each train to reach the engine at the front. As you run and shoot or avoid the characters you must also jump the gaps to avoid falling onto the ground but the gaps can be used to get to the lower part of the train. If you hit the ground then you keep running along side but can't get back on the train or advance and when you touch the left of the screen then you have to attempt that train from the start again.
