Thank you for your kind words. Makes me so happy to read this - I was so unsure if anyone can enjoy it.
Also much thanks for your feedback. All of your points are valid, and I have to find solutions for them.
The zombie horde was meant to be "announced" by an event card, telling the player that it will have passed the road at day X. But I was running out of time and didn't implemented this, so the horde just stayed there - numerous and dangerous. However, I once managed to beat all of them - but I barely survived and had a lot of luck.
Anyways, thanks again! Will play your game as well and give it a review.
