You have a sword, a gun and on later levels grenades and you must survive both macanical and "creature like" enemies that lunge at you or roam the land. I made it with only 15 levels because I am a solo game developer but the gameplay is hard so it should keep you entertain for some time for when you're bored. If you are nostalgic for a casual old school game like they made it in the 90's era I think you wold like this.
