that's a nice game! i'm sure if you'd improve one that you'd make an excellent game! add a story, (you woke up and found yourself in an abondoned house, with amnesia or sumthin) make a bigger level, add mice that morph into gigantic man eating mice and u need to start fighting them with weapons (nuthin common like guns or swords, more like find a stick, find mathes, find kerosene, use kerosene on stick, light stick etc) just a suggestion!
your birth was a blessing, sent to live and die on earth as a lesson, we each have a star all you have to do is find it, once you do, everyone who sees it will be blinded - DMX
