Secret Mines are bonus levels the player unlocks through finding hidden map pieces in the main levels. In the secret mines players must collect tokens against the clock to unlock chests of increasing value.
I created the pickup tokens and effects for the first iteration of the secret mines, and then for a later update, I created a complete visual overhaul of the mines. Working on completely new environment assets and systems to make the Secret Mines more rewarding and interesting. This included a system where blocks would have their material and cobwebs randomised, and guiding implementation of the new assets.
