Really fun little game! I liked that you sometimes even had to kill some of the characters to be able to move forward. All characters had their own important part in this and I really enjoyed playing it. One thing that gave me a bit of a headache was the way the camera moved when you swapped character. It wasn't that bad when they were close to each other but when they were further apart it made me dizzy, I do get motion sickness quite easy though so it might just be me.
Other than that I really enjoyed the game and would love to play more levels :D
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
