In fact, it's really not bad. Tetris and this type of games were you use your troops to defend your base against enemy forces seem for me boring. But the mixture of them looks nice. Very interesting concept. I spent some time playing this and did not regret it. Nevertheless, the game still has some problems. The game graphic is tolerable but needs improvements. Gameplay seems for me slightly unbalanced. When I try to do "Tetrises" (4 lines at a time) I can't, because the troops already damaging my base. And I play with a constantly held key "S", but I-figure can not appear for a VERY long time. Furthermore, the bonus for four lines is too small and game force you to make single lines all the time. Also, you can't get enough money to use expensive troops for this reason. And anyway, a large bunch of cannon fodder is stronger than any tanks (Soviets, what to say). Still, it seems to me that you need to make the game not easier, but fairer to the player. For example, make the multiplier for a combination of lines more significant and stuff like that. Well, good luck to you, comrade.
P.S Phrase "close to something" and "to close the door" have a "little" difference in Russian. So, please, don't use "близко". Use "закрыть" ( ͡° ͜ʖ ͡°). This mistake looks as shabby as possible for any Russian native speaker
