Good concept, I like how you used the famous "Kiki-Bouba" as your inspiration for this theme!
The movement is smooth and responsive. Big plus for having an instruction screen! I like how you can only possess enemies with lower health to switch sides.
-Though I feel like since this is a shooting intensive game, having players constantly having to click LMB to shoot doesn't feel good, I'd much prefer if I can hold my LMB to shoot.
-The recoil when you shoot feels annoying and it doesn't serve much purpose, and it confuses the players a lot when there's a lot going on in the screen. I often find myself not knowing where I am at the screen, or off screen.
-There's also no incentive for me to switch sides right now, from what I see as there's no penalties if I keep being on the same side killing the opposite side.
Overall, good job on the game! I wish your team all the best on your future endeavors.
