Hey Tosek!
First, thanks for playing the game! Second, I know its hard lol. I want to keep the game hard (for now), to challenge players, so that they try new things! However, I am adding new features every week, and as the player gets stronger, the game gets easier.
I've spent a lot of time the last few weeks working on unit response, and it should be much better next patch!
Some advice for beating the game: try to get a barracks early, followed by a workshop. That way you can get soldiers, and tunnel scouts out fast, and get a few traps up before the first invasion. A few good traps will cut down the orcs by 50% each wave, then your warriors and tunnel scouts can finish them off.
Again, thank you so much for trying out the game. I would love to hear more feedback on the next patch (coming soon)!
