One more thing, does monster spawners really spawns monsters? I mean the blue cage-like block. Because I know they spawn zombies?

нет, монстры таким образом не спавнятся.

Hey, the characters moves so fast compared to the background. I can barely see the player's arms or feet moving like its gliding on air while on the ground. It also falls too fast. I think you should lessen the FPS of the player and the mobs because they are independent of the FPS of the environment which makes them too fast I move 2 squares in one press. Hope you'll read this feedback and further improve the game. Thanks!

the translation into Spanish has an error back isn't espalda, back is atras

спасибо за замечание, я исправлю эту ошибку.

So dropping does not work or?
