Yeahh, I tried to design the levels in a way that you must first fail to understand the pattern and then adapt by knowing exactly what zombies are going to do. That’s why one mistake can lead to a disaster and why the pools are spawning after a second. But I definitly understand why it might be confusing.
No one told me that before but you’re completly right, I should have put the white background as the selected mode. My bad, I will remember it for the next jams!
I hope you still enjoyed the game and thanks for trying ! :)
