It's not only a good game, but also a good tool for genuine self-testing.
I love the psychological indications. The tests I have done when being diagnosed with various things, dyslexia among them, and several tests here are consistent with the results from those tests (Weak sides).
Not only do you 1 shot pretty much anything with an upgraded spearman, you don't die, and you can bloody defeat as many giants as you want without losing a single unit. Only by dodging their attacks (same thing with archers btw, I took down 5 of them just by dodging and doing an "achillies" on them)
Too easy, if badges are added, completing the game should be no more than medium. Hard badge would have to be "complete within 40 minutes" or so
