This is a fairly straightforward TD game where the goal is not to let the pathers reach your goal. There is a ranking to aim for in each stage, and each stage has an alternate nighttime mode, so theres plenty to do.
The game has a good upgrade system where you get exp by playing stages and earning achievements. Each time you level up you get a few points to invest in one of 3 upgrade trees, so you have some freedom in how youd like to beef up your towers, spells, and assist abilities.
Unfortunately, I found that after awhile of playing the stages became ludicrously difficult, to get the 3-star rating at least. It is basically necessary to use the super items you can get in the game by using a premium currency dropped by the pathers in game at a very slow rate. Of course, you can buy the premium currency using RMT! Sleazy level design, imo.
This isnt an awful TD game - its looks good and it plays well for what it is, its just too bad that it falls back of greedy incentivizing of RMT.
