HeartZ Co-Hope Puzzles

HeartZ Co-Hope Puzzles is a local co-op platformer from Upper Byte that blends light brawling, environmental puzzles, and a deliberately silly action loop into something best described as a couch game you pull out when a friend is already sitting next to you. You and a partner work through room-based levels, dealing with soldiers and machines dispatched by the antagonist Dr. Nylus, while solving the traps and mysteries each space throws at you. The verbs available to you are wonderfully absurd: kick, jump, bite, scare, and yes, fart. The fart is not a throwaway gag. It is load-bearing. That tells you exactly what register this game is operating in. The level design is the main event here. Each room reads as a small handcrafted puzzle, asking you and your co-op partner to coordinate actions that would be completely unreadable to a solo player. Upper Byte is a small studio, and the craft shows in the specificity of individual trap setups rather than in production scale. There is a visible logic to how each space was assembled, and when a room clicks, it clicks hard. The platforming is not particularly demanding on a mechanical level, which is probably the right call for a game that wants to reward communication and observation more than execution. What the game lacks is polish at the edges. With only 24 Steam reviews to reference, the audience is genuinely small, and that reflects in some roughness around feedback clarity and the occasional moment where the game does not communicate its rules as cleanly as it should. Some rooms will stall a session not because the puzzle is clever but because the solution's logic is slightly opaque. A seasoned puzzle-platformer player will push through that friction; a more casual couch partner might not. The tone is relentlessly cheerful, which helps, but pacing can drag slightly in the middle chapters before the level ideas hit their stride again. The visual presentation is functional rather than striking. It is not pixel art in the deliberate, hand-shaded sense I tend to love, but it is clean and readable, which matters enormously in a co-op game where two characters need to be identifiable at a glance. The soundtrack keeps things bouncy without calling attention to itself, a quiet competence that suits the game's energy without elevating it into something memorable. For a 2016 release from a small studio, these are reasonable expectations. Who is this actually for? Couples or friends who want something low-stakes to share a keyboard or two controllers over, players who enjoy puzzle-platformers that lean cooperative rather than competitive, and anyone with a soft spot for indie games that clearly had a good time being made. It is not a long game, and its scope is modest enough that it knows roughly when to stop. That self-awareness is worth something. HeartZ is not trying to be a genre statement. It is trying to give two people a fun afternoon, and on that narrower brief, it largely delivers. Kai, Scout Team
