I am amazed. The graphics are amazing and it did not expect such an entry in this jam. You should definietly add some screenshots to your submission, so that other people will notice this. 
The artwork, world, music and enemies are great. I feel that the gameplay itself is therefore a bit underwhelming. Like the other commentators, I would like some feedback for the shooting and also some sound effects. Minor improvements, that will make the game overall great. 

Keep up the good work! :) 

Wow I didn't expect such graphic quality, why don't you add some screenshots to the game page to tease about it ? Right now without playing it could as well be a 2D game made on paint !

Amazing work on the assets ! Thoses ennemies look great, i had a lot of fun jumping everywhere while shooting frantically. It would be neat with a little more feedback when you shoot  and hit opponents. Nice work !

Really cool assets! The game  looks  really cool and has a great vibe! I love how weird and unique the enemies look. It's a little hard to tell when my shooting works on the enemy though, maybe a little more feedback, there.
