Smartphone support + Golden Bot Challenge!!

The game supports smartphone browser!
This is due to our 1-button control scheme. We started with a 2-button control scheme but opted out of it for simplicity to make sure the game can be explained and understood as easily as possible. This smartphone support is coincidental but very welcome side-effect!
Golden Bot Challenge!
Having mastered our own game I am happy to announce a new meta challenge for the game - Golden Bot Challenge! To make the game more difficult you're supposed to build a full bot with only gold parts and win the game without selling it! PRO TIP: The collected bots and parts stay until the next days ;-)
I am excited to discover new ways to enjoy our dear new game! And without any actual modifications to the game itself!
Have you found new and unintented ways to play your game?
