It was only five dollars. It also looked cool, but for $5 how can you go wrong? I'm slightly disappointed it didn't come with trophy support, and like several other PSN games, it could use some help with its leader board display (take some hints from Super Stardust and Super Rub a Dub people), but its pretty fun.
Sorry, let me back up a moment, we're talking Elefunk. Its a cute new physics / engineering puzzle game featuring elephants trying to cross bridges that badly need some support upgrades. You add trusses, supports, ropes, wires, spans, etc. in an attempt to make them withstand the weight of the elephants (and other critters) as they cross. You're also trying to beat the clock and use as few pieces as possible if you want a high score.
The game plays quite well. Its not as complex as a bridge building simulator I once tried for kicks, but it appears to have some decent physics as they're implemented for the game. Note, as the game points out, that only joints can break -- pieces in between joints simply detach from said joints. Also, joints are always mobile; you can't make a nice solid beam 20 units wide, its like you've strung them together with putty instead of a good weld, but once you get the hang of it, its quite entertaining.
Have I beaten it yet? Nope. Got through the first few levels (up to one called something like "this is going to be tricky") before deciding to quit for the evening. I'll definitely go back and try levels over to do them faster or more efficiently, although it would be nice to see the stress on your joints in some type of colour coding before they break, to judge how close you got to failure. Also, trophies. Small puzzle games should all feature trophies.
The verdict? Definitely worth $5. Needs in-game music. Needs trophies. Very replayable. Could use higher resolution graphics -- somewhat blurry to me, not as sharp as Super Stardust for example. Music is so so, but crisp and fairly well recorded.
