For all interactions use mouse.
In Spiral Stairs, you’ll be controlling a cat with which you’ll be trying to climb on spiraled stairs. The problem is that there will be a ton of different obstacles waiting for you. You’ll have to dodge them all, else the game will end. It’s also difficult, since you can only move forward, so be sure to thing of when you want to move. The controls are simple and you just click with your mouse. In the store, you can switch the overall theme of the game. Try to get as high as you can, so that you can beat your own record. Good luck.
