Thanks! After each wave you must click space to call another! Each wave takes 10s.
You can drag and drop folders. When virus collides with folder, it'll lose hp. Folder have 3 durability. That means it can be hit by virus only 3 times.
Thanks! I'm a little dumb it would seem.
No, it's my fault. I forgot to add message to player that would tell him to click the spacebar.
