WATER FLOW

review | PLAYDATE

Developer: Torsten Kramer. 
Released: December 2023.
Genre: Puzzle.

​Water Flow never sets out to revolutionise puzzle gaming. Nor, in truth, does it seek to evolve it especially. However, with the Playdate such a distinctive experience unto itself, Torsten Kramer’s ode to Pipe Mania and the like acts as a top-notch consolidation for fans of the pursuit. Those wanting to relive the craze that swept home computers during the early nineties might be surprised by just how good a fit it is for Panic’s portable.

The setup will be instantly familiar: players must rotate a selection of straight, right-angled, and junction pipes to allow water to flow. Not only can the pipes be rotated, but the beginning and end blocks, too, whilst a few nice touches have been made to accommodate the Playdate’s smaller screen. The aim is to connect an unbroken circuit between start and end points, or continue long enough to achieve a designated score. Where it deviates most from the classic formula is in water passing out of the board (horizontally or vertically), resulting in a renewal of all the tiles used and the stream continuing from the opposite side of the board. This goes some way to solving the issue of a limited playing space, in conjunction with various hazard blocks that create some really satisfying brain teasers.

The water flow begins after just a few seconds, at a fairly pedestrian pace. The player can switch between three different speed settings via the ‘B’ button or the crank, though you’re afforded plenty of time to plan. Consequently, there’s less of the jeopardy you’d associate with Pipe Mania, as it’s rarely a race against time to stay ahead of the water, with most failures coming from misjudging routes or getting unlucky with void squares. You’ll face a bit of everything: non-rotating tiles (locked in the direction in which they’re displayed), countdown tiles (a number designating the number of trips off the board you’ll need to unlock them), and mandatory fields (blocks that must be passed through).

It pays to be circuitous in your routes, as trips off the board begin adding dead tiles, ones that cannot be interacted with and end the run upon contact. Linger too long without connecting to the exit, and you may find routes being fenced off. This produces one of the few genuine gripes I have with the game: their random nature, along with mystery blocks that can send the flow in any of three directions, results in a great deal of ‘random’ level failures, where the water is funnelled down a sequence of straight blocks into a void. With no way to mitigate this threat, a small handful of levels are a bit trying.

Water Flow wastes little on artistic flourishes, focusing instead on strong, compact design. The title screen is simple to the point of crude, whereas the theme and the system somewhat limit its opportunities for graphical expression. The direction of certain blocks (the starting point and mystery tiles) can be tricky to ascertain due to small icons, but for the most part, it’s clean and sharp. There’s also a handy Dark mode, reversing the palette and making things a little easier on the eye.

Water Flow represents tremendous value for money, outlasting a majority of Playdate puzzlers and available for a fraction of the cost. It’s a very complete-feeling puzzle experience: 70 levels form a durable challenge, especially when you factor in a three-star rating system that rewards higher-scoring runs. There are plenty of reasons to return: players wanting more can indulge in a simple but intuitive level editor, whilst Endless mode is a super-addictive, arcade-style burst of gameplay where the player must simply prolong the flow as long as possible. The added lure here is an online leaderboard: nudging your way up the rankings is really moreish.

Torsten Kramer’s Playdate puzzler takes the best of Pipe Mania’s legacy and sculpts it into something approaching a definitive portable interpretation. It clears a benchmark we often used to apply: easy to pick up, hard to put down. Water Flow fits the bill for both long, absorbing sessions and short, quick-fire blasts. It may not look a million dollars, and there are doubtless more original and more exciting games on the market, but for fans of old-school puzzlers, it’s an easy recommendation.

VERDICT
"An excellent consolidation of the pipe-puzzler. What Water Flow lacks in visual finesse it makes up for in strong design, tonnes of levels and moreish gameplay that's ideal for both quick-fire goes and absorbing longer sessions."


OVERALL: 7/10
