Hey I know this is a bit late but feedback is feedback I guess?
I loved the game's concept of the still enemies that made you angle your shots like a 2d shooter like Steamworld Heist, yet in a first person perspective! This gave a whole new twist on the FPS Genre for me! However the game has two main flaws that hold it back . First the limited ammo means you need to have about every shot perfect or it is suicide. Second the shield recharges far too slowly. If the goal was to have the player hide in a safe place because it is basically impossible to face these baddies head on, that means the only chance the player has to regenerate their shield is when they are out of the line of fire. So having them wait slowly while they are outside the line of fire doesn't quite makes sense so maybe make the shield regenerate in about a second? If you fix those two issue then you have a really solid foundation to build something special out of this amazing concept!
Anyway one thing I do want to mention is I'm going to make a Game Jam Spotlight Video on my favorite games from this jam on my Game Design Analysis Channel Etra Games in a few days! So here's a shameless plug to my Youtube channel if you want to be notified of when the video releases! :
