Update 0.18 - Lava Lanes, strategic maze building!

Hi everyone, Lava Lanes require careful placement of buildings without blocking access to the portal. If you struggle with this, or need a spoiler, I suggest that you watch our playthrough video. [url=https://youtu.be/GZf8dBhoXv8]Lava Lanes playthrough video[/url] [h2]New Content[/h2] [list] [*] New map "Lava Lanes". [*] 3 new enemies. [*] New research "Powder Keg", which gives a Pyro unit that sets off an explosive black powder keg! [*] A button that activates the in-game menu is now at the top of the screen. [*] When you choose a map to play, the previous map you played will be selected by default. [/list] [h2]Changes[/h2] [list] [*] Bugfix - use the correct icons for Aura Towers. [*] Place short mushroom stems to indicate where the edible mushrooms will respawn. [*] Bugfix - take all enemy spawn loaction into account when checking if a new building would block the portal. [*] Only show enemy health bars when they have less than full health. [*] Properly centre the "train" and "retire" unit icons in the building interface. [*] Bugfix - building icons are sometimes cut off at the bottom of the screen. [/list] Thank you for the reviews that came in, we only need 3 more reviews to boost the game's visibility. I hope you enjoy the new map and enemies! Till next update, André
