Pretty solid base to build off of. The enemy's behaviors all seem to be synced up, which makes it a little too easy to predict attacks and barricade with minimal strategizing necessary, so I would very much recommend desyncing the shots (i suspect theyre all pulling from the same action instance instead of having unique versions of that instance upon spawning).
It gives me the same sort of vibes as an old Madness Combat game I used to play all the time(huge compliment) and it's a lot of fun idle entertainment once you do get into the groove. There's a lot of good potential here, so I hope post jam you're able to go in and tweak enemy behavior a little and add additional stuff for the player to do as the game progresses.
Great job in the time frame you had! Keep it up :D
