Trouserheart is a $3-$4 (although I got it free as Amazon’s app of the day) hack-and-slash in the vein of Castle Crashers, although it is nowhere as good. You go from room to room and kill a random assortment of baddies. There’s only a couple of different types of rooms and baddies, so while it is random, it’s not really different. You get gold with which you can upgrade your equipment, all in the name of retrieving your trousers back from whoever who stole them. It’s a bit mindless and I found myself playing it a bit. Then I realized the game was pretty boring, but was too close to the finish to quit. There’s only 10 levels/bosses which you can finish in an hour or two. It’s worth it if it was free.
I am not familiar with the franchise but I gave The Great Prank War an Amazon Freebie try because it seemed to have an interesting tower defense mechanic – you start off with a couple of heroes and as you destroy towers, you get to build your own tower in their place. Unfortunately the implementation wasn’t actually that fun as the path to success seemed to be mashing buttons/hero special powers. It’s definitely no Kingdom Rush.
I’ve been playing the beta version of Hacked which is a game where you try and hack. If you don’t know how to program, this will be hard; but if you do it could possibly be fun? I played the story a bit and at the beginning you build up known functions (such as abs, mod, etc) from first principles. That’s mildly fun because you would probably never do that in real life. However, as I played more, the game just ended up feeling like work.
