I love the absurdity of the visuals! This submission was definitely one of the more eye-catching ones and when it comes to what I liked most about the game the almost creepy character designs are very fun and if you take this project further I think you should tap into this absurdity as much as possible and just try to make everything look as freaky as you can.
The game mechanics themselves are admittedly pretty rough and I honestly couldn't tell if the enemies had a lot of health or if my projectiles were hitting them at all because it would take me up to 30 seconds to kill some enemies and others would go down in about 5 seconds.
Definitely the most important area to improve is programming and I recommend getting more practice through jams such as this, it's rough in the early stages but the more you do it the better you get. Best of luck in your future development!
