This was an interesting one! I liked how you gradually scaled up, it's pretty satisfying to chomp down on fish that you've died to earlier. Didn't get much use out of the dash unfortunately, the attack was helpful for the boss though. I did have some performance issues, didn't impact the game-play too much but it was noticeable. VERY spooky vibe, loved the music change when you go down into the cavern and it's pitch black nothingness.
Got to the point where no fish could kill me, used the mines to end the run and get my score. The DNA collected number ticking up took like, 6+ minutes lmao
Pretty cool entry overall! nice work
