If you love tower defense games you must buy this. The game is well balanced, the UI is expertly designed with everything logically laid out, the tutorial mode is really well done, the music is good, the graphics are basic but functional, everything runs smoothly and the gameplay is sublime. I like that everything is so well presented and easy to understand. When you hit enemies, you see the amount you are deducting from their HP. I like that you can level particular skills. I like that you can buy equipment and it shows you the effect of the upgrade before purchasing. I like that you can undo skill assignments. I like that you can customize characters. And .... loot. I like that you can pause in battle and issue commands. This is VERY similar to Crystal Defenders, but where that game was punishing, had strange difficulty spikes and oppressive DRM (must have an active net connection), this game, thanks to more transparent RPG and levelling dynamics, never feels unfair - and is contains no DRM or IAP. There is a story, and it seems fairly basic but it is not important to the main game loop and you are able to disable all the story elements if you wish. I decided to watch the cutscenes as they are not too invasive or time consuming. I LOVE this game. I can't recommend this highly enough. My best purchase this year.
