Fifteen levels of clam-collecting with enemies and obstacles in between - and one of those levels is literally broken. Save your money for a real platformer.

I pulled up every available community signal on this one before writing a word, and the picture is not flattering. What we have here is a 2D side-scrolling platformer built around a single loop: guide your plankton character through each of the 15 levels, collect the required clams to unlock the exit, avoid enemies and obstacles, and move on. That is the entire game. No progression system, no unlockables, no ability upgrades, no branching paths. As someone who tracks decision depth for a living, the absence of any meaningful choice architecture is striking. The core mechanic - collect items, avoid hazards, reach the exit - is about as stripped-back as a game can get without being a tech demo. Enemies patrol fixed routes and the obstacle design does not evolve meaningfully across levels. The word 'hardcore' in the marketing implies escalating difficulty, but community accounts describe the challenge as inconsistent rather than well-tuned. There are no checkpoints within levels and no achievements to anchor any sense of progression. One reviewer noted the game felt like a "minimalistic platformer" suited mainly to newcomers, which is generous framing for something this shallow. The problems do not stop at design. Multiple Steam community members have flagged Underwater World as a reskinned Construct 2 template, functionally identical to several other titles published under the LTZinc and HandMade Games labels. Reviewers specifically identified at least a dozen other games that share the same structural template with only cosmetic differences. On top of that, the positive review score on Steam has been directly challenged as the product of coordinated fake reviews written in broken English shortly after launch - making the 71% positive rating unreliable as a buying signal. The game also carries a documented game-breaking bug: Level 9 reportedly contains no collectible clams at all, making it impossible to progress to the final five levels and rendering roughly a third of the content inaccessible. If you are genuinely looking for an entry-level 2D platformer to hand to a very young child with zero gaming experience, there are free browser games that offer more content and better construction than this. If you want a short, cheap platformer that will take an adult under an hour to exhaust (assuming Level 9 cooperates), the asking price still does not justify what you receive. There is no mod support, no community tools, no post-launch updates on record, and the developer has shown no sign of patching the level design error that blocks completion. For a genre that has genuinely excellent options at every price point, this one sits firmly at the bottom of the recommendation stack. Diego, Scout Team

GamerScout Verdict

Skip it entirely - a bug-broken, community-flagged asset flip with barely 45 minutes of functional content and no redeeming depth.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
