Greetings Junkyard Warriors!
First off, I'd like to thank the players who have provided feedback and suggestions for this game.
This is the first game I've ever developed and am always looking to improve things.
Speaking of suggestions, something I've noticed players requesting is additional content. Fortunately another game mode (or rather extension of the base game mode) is in the works! Improvements to the game engine have been made to allow bigger maps to be generated, towers and enemies to be more easily added, and improved efficiency which will make the new game mode possible.
In the new game mode, Harvest Reloaded, you'll have to manage and defend multiple mines from an endless onslaught of enemies as you clear the map, just like the base game mode. Also, as requested, new towers and enemies are in the works as well! The gif shows the current state of the new game mode as of this writing. The tentative date for rollout of the new game mode is August 15th.
