Thank you very much for the feedback, and thank you for playing! :D The slightly clunky controls were actually intentional (to represent a fish's struggles on land), but I was trying to not to go overboard on making it too difficult to control, so as to balance the challenge with fun, and not turn players away too quickly.
I'll see what I can do to further refine the controls, and maybe I could add another control mode that's slightly more forgiving (maybe smoother rolls; faster acceleration; more predictable jumps).
Originally the jump sections were even harder, so I'm glad I already made them a bit easier!
