Hey!!!! Yes, we noticed the enemy death bug after the submission closed so we will be fixing that once we are allowed to upload a new build. Also, upgrades are next on our list, our goal with this jam was to have a better proof of concept and playable version of our game loop which now is mostly there. After this jam, we plan to add more enemy types and add an actual upgrade system that ties to waves for player progression. Currently, you get max bullets, max health, and set move speed. We plan to break it up and add it behind upgrades along with powerups to complete the experience!
Thank you so much for taking the time to play the game and hope you had fun this jam!
