Hey! I played your game for second time. You improved it!

I am still fun of your fiction, it's just classic PC game "dark" theme :D

I beat the first level and next one and next one. Game has pretty great progression. I really like how you design unlock system.

I like animations of death, I still think you could add more simple animations on engine itself without doing pixel art to just make it more alive.

Yes, tutorial was useful. I was able to understand rules and beat levels.

Game feels much more polished and I enjoyed playing it. You got just pretty solid foundation for classic tower defense game. If you want to develop it further I feel you just need more "excitement" by more animations, particles effects and anything that could it make more juicy. 

Congratulations on your submission! Keep working!
