A very hectic TD game full of time limits. There is enough (too much) to do. Placing and upgrading towers as usual (very limited upgrades at first). Watching carefully and collecting the large coins in time (tap tap tap). Buying and engaging spells. Laying traps. Buying something with stars. Preparing (shooting) terrain. Sometimes you need to destroy one or more gates. Launching next wave early and again collecting coins (really hectic now). There are are few levels being completely different from TD mechanics (annoying). I played it for two hours or so.
There are 30 levels. Level #19 (the third one of the non-TD-typical levels; only traps and rockets—more a shooter) is hard enough that it feels necessary to buy IAPs
(I never will do so, so I am done with Dead Stop at this point). The unlocked survival mode of the first world is extremely hard as well (you can place only a limited amount of towers).
I wouldn't give it even three stars. Graphics, sounds and controls are a bit hysteric (p.e. when in rockets mode you have to tap/aim and can't collect the vanishing coins at the same time). A bit of all with overdone zombie sounds. Too limited, obviously a paywall before you reach level #20.
