Ok so no one seemed to be able to write anything up on this without seeming like a troll so here goes.
Game clearly is a port, it does have limitations, virtually no settings available apart from sound controls, ALT tabbing will take the game out of fullscreen (easily fixed by pressing ALT Enter afterwards), keybindings are locked (although this does not matter because the game is easy to control by default), and pressing ESC at any time will close the game immediately.
Theres the bad part, clearly not a huge amount of effort went into porting it, but its still playable.
The Good part, the tactics are reasonably deep, the game is not easy, comes with a fairly complicated advancement tree and from what I can see so far, quite a few missions. The tutorial explains everything in a natural way that is easy to learn, but hard to master.
Also, to the people complaining about the requests for the player to 'swipe' over a building, saying that this is impossible for a PC, they are idiots, who did not actually attempt to simply drag their mouse from left to right using the left mouse button. That is what swiping means, and despite the general lack of features, swiping works just fine.
Overall for this towerdefence genre, given its price at about 3-4 USD, this game is easily worth your time.
