Cool use of the theme! I struggled a bit on level 4, but finding the trick/timing for the jumps felt amazing
I'd like to see what you could do if you expend the game with more levels, techniques and/or masks :)
This was very chill game! I liked the idea of the timer increasing when we catch a fish, it's a nice twist
The music loop is well done and doesn't get boring or annoying. The only improvement I can think of is, as someone else suggested, adding another key to mash so that it doesn't get painful during longer sessions.
Great job!
