This game really hit on all cylinders. The gameplay was addicting and satisfying, music was great, especially the variations of increasing scariness, and it was just the right difficulty and length. I had a great time with it! I also it pretty satisfying to learn the different units' strengths and weaknesses (snakes all the way baby).
I did find the right and left clicking a bit counterintuitive, and sometimes my dudes seemed to want to run far away from where I wanted, but it wasn't problematic enough to take out the enjoyment.
