I really like this game.
The following are features I would like if they were added to the game.
Mining: Turn walls into paths. Takes time but maybe gives scrap.
Auto Upgrade: Robots automatically return to base for upgrades.
Auto Construct: Robots are automatically built using templates.
Wrecked bot removal: when wrecked bots are empty it would be nice if they disappeared.
Auto Repair: automatically repair items that you pick up. (auto scrap given priority)
Robot Roles: assign roles to different robots to focus on different tasks.
Enemy Bots: weapons, armor
More upgrades.
