Sounds like you ran out of time, but that doesn't mean you have to give up!  Once the voting period is over, take this as a starting point and keep going :D

Can't say it is a bad game because there isn't anything there to call it a game yet. The gameplay area is minuscule but the camera follows the player anyway allowing you to see beyond the play area. I would recommend blocking the camera for small levels, if you are going to have the camera follow the player try to learn to place limits on it so it doesn't show anything beyond the play area. Another recommendation is to create objectives.  Unless it is some kind of sandbox game there should be a winning condition and there doesn't seem to be any here. Defeating all your enemies, collecting any number of objects, surviving a certain amount of time or enemies and/or reaching the exit are some of the most common objectives in a game. Don't be discouraged if it was your first attempt and you didn't have enough time to finish this time. Consider it a learning experience.
