I do like the concept, but the gameplay wasn't very fun. Trying to shoot the air enemies was very difficult because of the time it takes to shoot another bullet, and there wasn't much feedback on the enemy health, not to mention the enemies continuing to spawn in before I could properly deal with the others. 

I do think that with some more time, it could be a very wacky and fun shoot-em-up, so good luck on that!

i like that everything is hand-drawn, especially the fullscreen button
