I don’t know about you, but I’ve noticed something of a trend on the Android Marketplace, and for that matter, on most arcade-game style marketplaces – the appearance of wave after wave of tower defense titles. Their popularity has soared to the point where it’s hard to envision the indie games market without these titles.

Of course, there are big-budget versions – DoubleFine’s “Trenched” is a good example of the fact that major studios and developers are paying close attention to. Whether you’re looking at gaming phones on o2.co.uk or browsing flash game sites, it’s hard to ignore the appeal of the strategic tower defense genre.

But what does that say about games and how we perceive them today? There has always been a definable gap between the casual and the hardcore, with those few perfectly-balanced in betweens finding fame and fortune. But tower defense titles are in an odd place – outside the Venn diagram that helps us define the current swathe of video game design ideas.

Specifically, it’s because they are games that are at first, enjoyable and casual, but soon become a hardcore experience in their strategy and depth. With no discernible means of altering difficulty levels, and certainly no way to tell if the cartoony, simplistic feel to earlier experiences before it becomes all about stopping the mobs from crossing beyond the point of your reign of destruction ever actually dissipates.

It could just be a phase – there’s nothing wrong with capitalizing on the gaming audience’s sudden urge to endlessly build militaristic architecture in order to fend off hordes of hostile entities. But once the gaming crowd moves on, will there be a niche? Presumably – all games survive to some degree, even just in memory. I hear Backgammon’s still going strong. But it’s key to note that while tower defense is the big thing, it’s best to jump on in. The design is straightforward, the appeal is huge. If you’re curious, start work. You could just fund an entirely different project.

When I first saw this game I’ve immediately fell in love with it. It is amazing how simple idea can make such a big effect. There are 20 levels and in each level you have to move object from 1 area to another. There are many obstacles and you can build your own vehicle, or whatever you want just to reach final area. Best of all is that you achieve your goal in many ways, it’s just up to you, how you build your physics “thing”. Author also offer saving of your scene, so you can paste link to your friend to watch your design. For sharing upir design, there is opened forum, where you can find many funny and incredible designs made by other players. You can find some interesting design at the end of the post. There is also possibility to Buy full version for $10 and you can play and buiod your custom scenes. But be aware, this game is sooo addictive. I just can’t wait to find free time to play game again.

Here are some my designs (but be aware, if you don’t want to know solution for that level, check it after you solve that level)

• Magnetic Dinosaur This is not solution, but amazing Magnetic Dinosaur If you upgrade him to move ball into goal, please let me know
