Great TD game, for many reasons: 1. "towers" efficiency varies not only with upgrades, but also with different kinds of enemies: this makes money less important - and timing, strategy and troop placement much more important. 2. Building your own army is part of the strategy as well, leaving you the chance of building an army adapted to your defense style. 3. Quests are hard but can be solved with fewer units than you would guess, if you select, place and update them correctly. I agree on the other hand that a better inventory management would be great. And also maybe a simpler way to upgrade troops during waves - that would also avoid some lagging when bunches of necromancers occupy the map and you have to run with your mouse from one unit to another trying to upgrade it correctly in real time. Still, definitely a big fav for me. Thanks to the developers.
