This game is pretty fun to play, and I feel like I need to speedrun it more to get a more respectable score to showcase on the leaderboard. The sound design is AWESOME! I really like how the music gets muffled while you are underwater.
To be honest, I don't think I would change anything from this game.
PS: But it would be nice to have it like jump king where you lose a lot of progress when you miss a jump. Rage games FTW lol. (Just a joke. Don't make it a rage game T_T).
