This has a simple yet effective central gameplay hook (the concept of having to submerge a jet ski is funny to me), though I'm not sure how to feel about the inclusion of upgrades, or at least how they're handled. Health drops being something you need to unlock in the first place seems strange for this kind of game, but then once you do, the game becomes really easy and doesn't escalate. Personally, I feel like the cosmetics are a good enough incentive to collect the cans.
