Let's get right to the heart of the matter: Splash Or Crash is about throwing things down wells. Ten wells, actually, if we are going to be painstakingly precise.
Each contains a variety of hazards - from oversized biscuits to rotating planks of wood - and you control whichever projectile has been hurled down there, guiding it with the Circle Pad out of harm's way and through the speed-boosting doughnuts (no, seriously) until it splashes down at the bottom.
And you know what? It's not bad. The 3D effect is startling - a little too potent, even - while each item, from a bog-standard rock to a watermelon and a Russian doll, has its own properties, and even a brief backstory (one of which manages a nifty Street Fighter gag). If you're struggling, even with the HP boost you get by popping balloons on the way down, you can use the bouncy ball with its infinite HP to unlock the next well.
It's obvious Poisoft is happy for players to reach the end within 20 minutes, as the longevity lies in chasing high scores. Which would be fine, except - criminally - there are no online leaderboards. Still, as games about throwing things down wells go, Splash Or Crash is right up there with the best of them.
