Hi guys, the first major update is scheduled to mid April, where we'll be adding a brand new map (larger and more difficult than the current ones) and a new enemy type (surprise).
The plan is: a new map every month!
I'll be making some balancing too, increasing the enemy's spawn rate for added challenge. If you think the game is currently too easy, try going to the main screen - settings - advanced tab - difficulty level, and increase it to 100.
Thanks for playing, have fun!
