Unless I misunderstand one of the mechanics, this is more than a day of content. However if you intend to be very active at the game you will be disappointed with difficulty spikes, where the time required to begin the next activity becomes huge when attempting to do arctic diving.

If you are a filthy casual I highly recommend using dev console to advance over these difficulty spikes so you can continue the interactive experience without need of waiting.

The game does not explain to you why you fail to dive at the various oceans. This is frustrating if you don't know what to do. (should have rated 4 just for that).

Just like other MrRedShark77 games it's clean, straight to the point, and involves multiple tiers of prestige, and continues with that innovation by making each tier a different mini game.
