Use WASD to move, or the arrow keys, or even the space bar. Use S or the DOWN ARROW to go through doors. The mushroom box makes you 2X larger and allows you to cross gaps easier. The mushroom only lasts 15 seconds so don't wait!
This game took me a while to make, and to be honest, it didn't meet my expectations. But nothing does so it's not abnormal. I hope you enjoy this as much as I enjoyed making it. I do intend on making updates. And think of this as the "expansion" to Cat Jumper Ultra. V. 1 : I wanted the mushroom power to make you jump higher but instead it made you big just like in Mario. I do intend on changing this in V. 2. V. 2 : It fixed glitch I found where you can jump midair. I also added a new picture.
