So basically it’s actually pretty easy, all you need to do is beat the game as normal and make it to the last stage (300) of the last tower (the third tower). Then all you need to do is use the stage selector at the top of the screen to go stage 0 or the lobby. You can do this by typing 0 or pressing the right/up arrow which will automatically teleport for you.
Sorry for the inconvenience and late response. We’ve submitted a fix for this issue and it should be available shortly. Your guide is correct and now works as intended! Thanks for taking the time to write a guide on our game. Appreciated!
We intend the secret to be a small side-quest rather than a main gameplay objective and as such we want to encourage players to complete the full game’s content before exploring the rest of the tower(s).
