First levels are harder than mid-late game levels, at least for me. Keep trying, and once you get through it you'll crush the rest of the main campaign

because its a hard f game

i don't think you suck,the Warrados said it pretty well

In this game you can't build the same stuff you do in other levels. Try putting things in different places. Some levels are no good with armored militia protecting you. Others the "tower" might be one of the best things to use. It's as much about experimenting as it is about grinding out the victory.

Piece of advice, you don't have to get 3 stars on first try, just try your best and go to next stage to get more stars. That way, you can have more stars to upgrade your towers.

They changed the enemy health with the item shop update. You're gonna need a few to finish the game.

Just learning the basics will go a long way
Enemies have 2 tyes of armor: magic and physical
Magic towers deal magic damage and are stopped by magical armor while ignoring physical armor
Every other tower essentially deals physical damage and are stopped by physical armor while ignoring magic armor
Barrack towers are unique in that that they aren't supposted to deal damage as much as just stop units from advancing

You can't rely on just one tower, you need to use all of them
Also some heroes like mirage are garbage while others like boneheart trivialize the game
Remember to always use reinforcements to lock enemies in choke points and use meteors only when there are a lot of enemies grouped or if you absolutely need to take out certain enemies

Hope this helps

What about the shop items?

In other KR games I have a power, but here this bomb, freeze etc consumables. They kinda expensive, not very useful, and are wasted on failed matches.

Yesterday I used the one that gave me 5 extra hearts, and it granted them to me, but still failed (I used them too late it seems)

Does people use cash shop items at all?

This post is pretty old now.

You never know, I may reinstall. I estimate the probability at around 18% that I try the game again within the next 3 days after making this post.

Oh, hi, you're still around lol.
