I actually really like the tank controls and when you pull off a good escape from a shark it feels really good. That being said you kinda need to know a shark is coming up and know where the exit is to reliably escape from it, so I felt like I could only progress by dying and then trying again from the top. Which I did a couple times because I found the gameplay was so fun! With a little adjustment in the difficulty, I think this could be even better. Great entry!
