On the menu, use the left and right arrows to select a level, and use the up and down arrows to switch series of levels. Hit the play button to start. The ball will go to your mouse pointer. With this new update, the special tiles vary from level to level. You can, however, turn on Classic Textures in the updated levels, which will simulate a similar experience.
This is a "full" game, but it's technically not official. I did have permission from @kilonap to create one, though, so long as I credited him. So I'll do that now. @kilonap created the engine which (with a very few changes by @waffledragon) is used to run this game. He also created some of the levels within the game. Long story short-he made the game, some other people added some levels, and I put them in one place. People whose levels are in this project: + @kilonap + @waffledragon + @lexdoesgames If you'd like to add a level to this game, please comment on this game or on the Kilorush Custom Levels studio: https://scratch.mit.edu/studios/5182717/
