I love all the different mechanics. Of course it's tricky when you have limited time to teach them to the player. Presenting all that text on the screen is not ideal, but I can understand why it's there.
I had the same struggles as others with the controls. However, I appreciate how the swim and shoot mechanics are designed. It's too tricky for me personally, but it's very obvious that great care and attention went into the game.
Awesome job, team! Good luck with the game jam and on your future projects :)
