Highly repetitive
The game is highly repetitive in gameplay and strategy, the different helps reduce this, but does not change the strategy, flash/stun/shock/smoke/rocket basically completes the exact same purpose of cleaning and area inside a room, and probally Will work the same if the room is small. flashing 10 room is fun, flashing 1000 similar size/similar content room gets boring fast. Furthermore, the long press work very bad on surprising enemies (eg: too many door to block, 2 come in before block completes, etc). just add a gernade button that you can drag to quickly throw gernade. Capture enemy after they surrender also adds Nothing to the game as they always stay still, pure pain. Add more irregular shape room, reduce room number per stage/ bullet blocking furniture/more enemy type/better Ai (eg: run or call support)/allow equipment selection/add alert level(make enemy stronger)/allow individual Unit task assign Will make the game experience better.
