Rat Maze 2 is a browser based game with cute pixelart, oldschool chiptunes and equally simplistic and retro gameplay. Basically you're this albino rat and you have to run around a big maze and find all 72 pieces of cheese, as well as the letters that make up the word 'ratmaze'.

The pieces of cheese are usually out in the open but the letters are harder to find. One of the A's is visible in the above picture but to be able to get it you need to sink all of the balls without sinking the black one. There are a few secrets to discover, like walls you can pass through and underground tunnels that take you to another part of the map. It may take you a few times to get all of the cheese and the letters and then something else happens, but I won't spoil the surprise.
Overall the game has a charming retro feel, is very compulsive for a few goes and isn't too frustrating (except when you've only got 1 or 2 pieces of cheese to find and you've looked nearly everywhere!). Plus I got the top score for today too! I give it 7.5/10.
