i was up to the 31st or 32nd level, but had to get up to get the door. Couldn't find a pause button either, and when i returned I was dead. not quite sure what got me. audio and sound effects were really low, barely could hear them and couldn't find any settings. Last thing is, I was confused on how the tower upgrades work. It prompts me to click a tower to sacrifice, but it only works randomly, or am I misunderstanding something? Overall I enjoyed it, the visuals were the best part of the game. The T posing boss was my favorite, I know it is a bug, but it was cool to see a T posing kaiju.
