Easy to understand concept and gameplay. Growing the horde is fun and satisfying however as others have pointed it does feel a bit mindless as in there is little challenge offered back, our zombies just seem to be able to overwhelm really easily even against the shooting guards and landmines.
The simplicity of controls did leave me wondering if there were some other "hidden controls" that i wasnt aware of for example i was trying to click to understand if something would happen like boosting zombie speed or splitting the horde.
Music is fitting and gave a nice goofy ambience. Definetly has some potential of growth trough some level progression and challenge ramp.
I played the Web Version which also lagged a little bit but it wasn't a consideration to my rating.
Good job!
