The gameplays and controls feel right--credits to you for creating such a smooth gameplay within 3 hours! The enemies are a bit too easy; however, they add a nice touch to the game.
My one feedback is just to add a soundtrack to some of your recent entries---all of your submissions has brilliant ideas and gameplay, in which an audio track will definitely improve. Just a non copyrighted looping bg music will be great. For example: I have been using Kevin Macleod music for my past 5 games or so lol
Great job!
