Really nice concept for a game, i found pretty quick i could just spam 'L' to do infinite damage and not take any damage, the music though is really cool! I was confused by using L to do damage, i didnt properly read the controls and just thought it would be left click so i was a little thrown by that but it's nothing major obviously :)
it would be nice if there was more to explore and different enemies around, great first game overall though, good job finishing it! :)
