This game gets a recommendation, but just ever so barely.
It's a sad decade for Marble games for certain, but I'd be lying if I didn't say a lot of them conjured up some very creative results. Lost Marbles is a creative game with an interesting concept of using teamwork between different elements of marbles to get around obstacles. Alone the concept and ideas are extremely spot on, but they fall short due to the wonky 3D perspective and extremely harsh clear times, and while I am enjoying the game, these problems are hindering me from enjoying it more.
One thing I'll make clear: The par times displayed in these levels are very difficult to pass, even in chapter 1. Par times this strict should be renamed to challenge times instead. Par times are flexible time limits that allow for the players to clear the level efficiently while still allowing a few hiccups here and there; the time limits set right now are NOT par times.
The other qualm I found was that the 3D perspective is pretty unusual in some areas. It's probably because of how plain some of the platforms look that there's not much depth to them, and because of that it makes it hard at times to judge the length of a jump.
There are other problems like Hardcore mode not letting you keep your unlockables if you die and have to restart older levels again, and the fact that that the hole you jump through in Fatal Attraction needs some serious fixing.
Take it from someone well versed in just about every marble game in existance, this game is far from perfect, in fact it is just boarderline tolerable. Lost Marbles does have a very fun concept, with some outstanding ideas poured in as well, unfortunately with the problems stated above it hinders the enjoyment of what is a really innovative game. The game graphics are also pleasant to look at, which is unusual because the menu GUI is very below average. Essentially it is hit or miss in all aspects, but I guess you can say the pros just barely outweigh the cons.
