Slow, boring, broken attempt at tower defense version of Torchlight
There are two critical flaws that immediately impair the games enjoyability:
1. PAINFULLY slow character movement (including the need to walk and physically touch things all over the map just to progress between rounds). Almost all of these functions, particularly simple tasks such as "start next wave", "auto-collect loot from MY kills", and "look at clues for all portals in the next wave", could have been automated from a single screen.
2. Atrocious menu design. The simple acts of character and inventory manipulation are atrocious. If you've ever compared a classic JRPG's menus with a classic NA-RPG's, then suffice to say this is far to the "click-heavy, muddled mess" JRPG side of the equation.
Combat is likewise slow, and just never seems very intense or impactful. It takes a considerable amount of time just to clear all waves of a map, as if they're trying to milk this broken formula somehow. Traps similarly never feel effective, and the method of placement, rotation, and repair is cumbersome at best.
The game looks, sounds, and co-ops rather well -- it's just far too slow and irritating to actually enjoy.
