OMG I loved this so much. I timed it and I spent about 25min on it. I loved the style and the gameplay mechanic and I'm really happy you didnt punish us by starting us over because I absolutely would have quit and was about to the second time I failed on the boss.
I really liked it though and kept going because the zombies gameplay I loved and could memorize way longer patterns for later levels, and the ghosts were straightforward, but the bats were messing with my brain (I understand it 100% logically but in the heat of gameplay it was really difficulty) so I never got the hang of the boss just kept getting one hit in and dying and finally winning!
Thank you!
